Cisco Switching/Routing :: 861 Router - Slow Internet Performance
Jul 21, 2012
I have a new 861 router which I have connected to my home broadband cable modem. Got it all working okay and I have access to the Internet but its not as fast as it is if I connect my laptop to the modem.
My Internet is 60mb (was 100 but I downgraded). When I cannot my laptop directly to the cable modem, I get 60mb download speed on speedtest.net If I connect the router's WAN port back to the modem then I roughly get about 40mb, sometimes even 50.
I do not have any IOS firewall configured on the router, just basic ACLs to stop SSH and TELNET from public networks. If I do enable firewall then my Internet connection halves itself. I have read around that this is the case with ios firewalls on these small routers so I've disabled the firewall but I still don't know why I cannot get full Internet speed.

I am currently having performance issues running a 3 x stack 3750G (different models) as a core for a network of roughly 12 x distribution switches. [code] As above, I have a 12 port Fibre switch and 2 x 3750G-48 port switches. [code] I tried to change the SDM to route but hit another issue where the 3750g-48 does not support SDM route so I had to revert back to desktop VLAN.Could the SDM Template be the reason for slow performance? If so which SDM Template should i use as this is the Core L3 switch.

I just moved into a new apartment. It has Comcast performance internet (16mbps). However im not getting anywhere near that. I have it connected via ethernet.
I tried speedtest.net and my result was 1mbps download. ping of 225. Web windows take forever to open

When mutiple Policy based routing configured on 7600 routers, did the router performace degraded with the number of policy based routing rules?Also, did 7600 running 12.x use per-flow based routing or per packet based routing?

I'm experiencing quite a slow vpn performance. I've tested different scenarios.* Windows XP with built-ín pptp client and Shrew ipsec client* Linux built-in pptp* wireless and wired connections? I never managed to go above 1MBps neither with windows or linux. I managed to go up to 3MBps using the Shrew client.I've also checked mtu settings and everything seems to be fine.

I recently inherited a small network. There is an existing 1.5mbps Internet connection (fa0/0) (includes MPLS as well/same provider). We added a new ISP that allows for 50mb down/5mb up. I added the new ISP to fa0/1 and modified the NAT overload statements accordingly. I alo changed the default route to ONLY use the new, faster ISP connection. Using speedguide.net, I am only able to get 6 to 10mb down, most of the time. if I plug a laptop into the cable modem then I get 37 to 50mb down. Why the 2811 is so slow?
I have attached the config and various show outputs (nat, sh ver, memory, etc.). the file called "latest logs" contains a "sh ip traffic, sh int switching and a sh proc cpu sorted". [code]

Is there any official Cisco reference to describe what is considered to be the highest acceptable production CPU load on 2800 routers? I found the document "Integrated Services Routers G2 - Performance Overview" that states at page 5,Most service providers set their CPU alarms to 60 or 65 percent. Many enterprise customers are comfortable running production networks with CPU around 70 or 75 percent.

on fwsm we have different dmz for different application. mostly of Oracle (1521 port) to application means seperate one. problem is oracle people reported the slow performace when exporting dump from once vlan to another. before that they are using 3com technology (network) and on this its ok. time difference is double from old to new.
i had sniffed the traffic also and found alot of TCP OUT OF ORDERS errors. i read that this is the bug which is resolved in 4.0.

I have a shitty WRT54G right now, and its slow as heck. I was thinking of getting this:
URLS ,I know the later is a modem and a router as opposed to just a router in the first link.I have comcast, I hear it uses Docsis 3.0 right? Mine is a 2.0 modem right now.

Pure 3750X-48PS ip base stack.One switch reboots from a power issue (possibly the master switch? Haven't confirmed yet in the 3 cases I've seen)The rest of the stack stays running fine (as it should), the rebooted switch rejoins the stack just fine
What I've observed after this scenario takes place is that network throughput on any port in the entire stack is severely degraded. Prior to the one switch rebooting, I can hit gigabit transfer rates going anywhere on any of the switches in the stack. After one member reboots by itself, I typically hit a transfer wall around 5-20mbps in one direction and sometimes better going the other direction. I've only confirmed this on 3750X stacks and I can replicate it every time. Newest code I've experienced it with is 12.2(58)SE1. I have not seen confirmed reports of this on older 3750 (E, G, plain) stacks of which we have a ton of.
Rebooting the entire stack so that all 3750X members are coming up at the same time solves the transfer rate issue every time. I would think there has to be a better way to get performance back to normal or prevent the performance hit in the first place.

Supervisor Engine 720 options support centralized forwarding rates up to 30Mbps and distributed forwarding rates up to 400Mpps. I never understood the claim of forwarding rate logic in mbps. How i can load the 6509 box to check this forwarding rate?How can the performance increase from 30mbps to 400mbps? is this just because of DFC on all the line cards if yes does it mean i have to add the DFC on SUP as well .

I have a network coming up for a switch refresh. Management is pushing for 2960s and I would like 3850s. We are running Cisco Voice and Video over the network. I saw a few things that seemed to be in favor of a Layer 3 switch vs. a Layer 2 switch. Some items like better performance due to switching based on IP vs. switching based on MAC. Some information that will show the 3850 to be a better choice or that the 2960 is capable.

Will a MTU mismatch in Nexus 7000 affect the performance ? I have a nexus 7000 at one end with MTU set to 1500 and Melanox bx5020(Storage switch) at other end with MTU set to 9600. Storage team is complaining about performance issue related to slowness.Does MTU mismatch plays any role in slowness ??

I have an RV042 VPN tunnel with an RV082.The RV042 has a public IP Address obtained by PPPoE, the RV082 has a public IP Address obtained via Static IP.The problem I see is a really slow performance. Both internet conections are idle and the performance is about 2 or 3 kbyte/s My question are if I should I enable any of this:
- Agresive mode
- NAT Traversal
- IP Compresion
- Dead Pear Detection
How can I troubleshot this slow performance?

I have a WS-C3560G-24PS service as a distribution switch with six (6) WS-C2950T-24 connected to it. In looking at the utilization on the inter connect links no one is running close to a gig speed and this includes the link between this switch and the core. The CPU load (6%) and memory utilization (30%) on the switch do not seem bad so what else does one watch to see if it needs an upgrade?
We are starting tohave discussions about any needed upgrades on the network. I have an ocassional user that complaines about low performance but looking through the network I can find nothing glaring on a consistent basis that says an upgrade is warranted. I am however looking at things such as the above. Utilization on links, CPU, memory, etc.

I am on a call right now troubleshooting some latency issue. The CPU usage on the sup card is low. Don't see any drops or input errors. I am aware that the switch and its modules have capability limits. Is there command I can run which will tell me if any module is overloaded or if the fabric/backplane is over utilized?My chassis is WS-C6513 and sup card is WS-SUP720-3B.

I just switched from xfinity to brighthouse networks after moving and now my desktop internet is extremely slow. I did lower my internet speed from 15 down and 3 up to 7 down .5 up. I realize that alone will make it slower, but this is ridiculous slow and its just on my desktop. My labtop is fine, but the desktop takes 15-20 seconds to load this page.Have ran spybot, and windows security essentials scan and all windows updates.
Speed test on desktop:
Down: 6.8m (847kb/sec)
Up: .5m (61kb/sec)
Setup:
Amd Athlon II x4 635 @ 3.2 ghz
MB: Asus m4a785td-m evo
2x1 gb kingston hyperx
windows 7 home premium
Everything else on the computer runs fine, all windows and programs open normally, however I can not connect to the steam network. Makes me think it is router or modem related.

Everything in my network works as a charm. Every host in my vlans can access and ping the internet with no problems. But, my main router does not ping the internet (Pinging either ip "173.194.71.104" or domain "www.google.com" do not work). I don't know how is that possible since my hosts can ping the internet. Below is my main router confiurations

I currently have a dlink dir-655 in my basement. my computer on the second floor is connected via DWA-160. I Only have around 2-3 signal bars, and never get the 300mbs like described. i would like to know all the possibilities to extend my range (to have 5 bars) or get better connection speed. do you recommend an access point or an extender? Which models? also, if i have an dir-615, can i use it as an acesspoint/range extender for my computer on the 2nd floor? if so, how? I am looking for the cheapest alternative in order to have better signal and speed. The modem is stuck in the basement therefore I cannot move it.

Despite all the drama regarding the DIR-615, I've had the B2 revision since around late 2008 or early 2009 (can't remember exactly, most likely late 2008) and it had been working flawlessly. And I do mean that. I never once had a problem with this router and highly recommended it. Back then I was on a 24/1 connection, and had been up until recently.
Now I'm on a 100/10 line, and things haven't been looking too great. The internet is stable for the most part, and I am getting full speed, but the router has been starting to drop its connection a lot. I've had to release -> renew (or simply restart the router) quite often now and it seems to be happening at complete random.
weaking with settings, updating firmware, etc but no luck. All connections in question are of course wired, not wireless.

I am seeing on my 3750E series switches (WS-C3750E-48TD). I have multiple VLANs configured on here, one which is used as a 'workstation' VLAN. I have an inbound ACL applied to the VLAN interface *(int vlan 50 to be exact). This list is admittedly long at roughly 6000 ACE's. Now I just recently installed these switches as they replaced some 4507R switches which we moved to our new centralized DC. Here is the issue I am having. This same ACL was applied to the same VLAN interface on the 4507s when they were doing the work of the 3750s. What I used to be able to do was actually edit the ACL by removing it with no ip access-list extended WS-In and then followed up by the ip access-list extended WS-In ......and the lines I wanted in the ACL. I know I could use the line numbers to edit the ACL but this worked OK for me. When I would do this on the 4507R, the ACL was still applied to the interface but traffic never seemed affected by the removal and re-adding of the ACL. I did this by copying and pasting the ACL into a terminal window. It seemed as though on the 4507 the ACL was not compiled until the entire thing was in loaded in and therefore traffic was not processed by the ACL until the load was done

I have 2 new 3750g devices in a small environment. switch1 acts as our collapsed core and has ip routing enabled, and is connected to a ASA 5510. There are 3 HP l2 switches connected to switch1 as well. switch2 is simply a server switch. switch1 and switch2 have a 2port etherchannel between them, and a vlan trunk carrying 4 vlan's. traffic between any 2 hosts on switch2 (same vlan) are slow. (average 300Mbits/sec) If I move one of those hosts to switch1, speeds increase by 3 times. (average 900 Mbits/sec). Additionally, traffic between any 2 hosts on switch1 are quick. testing is done with iperf as well as timing 1gig file transfers.
I don't see any errors or drops anywhere, and there are no other symptoms other than slow transfer beteween hosts on switch2. I just got 2 more of these 3750's to put in a 2nd site that we have, put a quick configuration on them, and have the same result. Other than switch1 having ip routing enabled, the configs are pretty much identical.
