View 1 RepliesIs there much of a network speed difference between a green drive, Seagate Barracuda or a regular drive?i.e. would you see greater network throughput with a 7200 RPM drive compared to a 5900 RPM drive?

I see an option under security > SSID Manager on the web interface to select an interface of Radio0-802.11G, Radio1-802.11A or both. Can I put the guest network on the Radio1-802.11A and make it more secure/bandwidth limited or does this option not matter?
View 3 Replies View RelatedI'd like to see some REAL LIFE comparisons of ASA firewall throughput (a bit like this one for ISR G2 Routers - [URL].
The reason I ask is that I recently upgraded a firewall from an ASA5505 to an ASA5520 on a small network where the only outside connectivity was a single 10meg Internet circuit with an IPSEC VPN (not landed on the firewall but on a router) to another site.
When I swapped out the firewall the users noticed a big improvement. The firewall is not doing anything out of the ordinary - no IPS or VPN, just standard state full inspection.
My first wireless router, which I still have and works perfectly, was a DIR-601, A1, fw v1.00na. It has always been reliable and worked great, save for being a little weak on the signal range. Back when I got it I knew little about networking period, let alone wireless routers- so I never tweaked anything on it. Now it's almost 4 years later. Being a little more knowledgable, and my family creating A LOT more traffic on my network, I decided some upgrades were in order. First I called COX to upgrade my speed too, which led me to having to purchase a new Motorolla SB6121 modem- and everything was great. However, aside from the same old dead spots in my house, I was starting to realize the limitations of my 601 with regards to handling the traffic load. Since I never had an issue with my 601, I decided to stay loyal to D-Link. After, albeit, a small amount of research... I decided on the 655. It fit the budget, and I read some decent reviews on it regarding gaming. Plus, from what I've read, I didn't really see any benifit to justify a dual band router for what I do. Anyway, my new 655, B1, fw v2.05NA has solved all of my wireless issues and handles our traffic perfectly, except for one slight problem- my wired PS3. I have Cox ultimate, which here in Nevada is up to 150Mbps, and wired my laptop is getting 107Mbps download- pretty consistently with the 655, and around 100 with the 601. My PS3 on the other hand, went from 27 to 32Mbps wired with my 601, to only getting 8 to 15Mbps wired to the 655- and a lot of lag on certain online games. It seems that out of all of our devices, my PS3 is the only one that doesn't like the 655. I really hesitate to DMZ my PS because of the risks, but at this point I'm almost desperate enough to try anything. I hooked the 601 back up for now for the PS3 performance...but we are REALLY missing the wireless and traffic handling performance of the 655!!

View 2 Replies View RelatedI have two NAS drives directly connected to my router. I am accessing them through my XP laptop's wireless connection. I am trying to copy a large volume of data from one to the other (28Gb).The problem I have is throughput. I am barely getting 250Kb/s from one drive to the other.Is there a way to speed this up?
View 2 Replies View RelatedI need to provide a router to connect Internet circuit and run IPsec to MPLS network. Circuit is 10Mbps.
What is the max a Cisco 881 can handle if running IPsec?Also, if you are aware of any branch router (1941) which allows connection to future 4G LTE .
We have a 1841 setup with WAN and LAN subinterfaced(2 WAN connections, 1 internal VLANs) and I am recieving some pretty horrible throughput when traversing the router to the WAN.
I am receiving about 2 MBPS down but around 5 up.Currently there is a ACL on the WAN interface, and as well we are running NAT NVI. It is possible that this might have something to do with it, but I am not sure.
Most of the CPU is going to IP input however I cannot seem to determine the cause. One thing I am thinking is the overload for NVI is using a route-map. Could that cause it to process switch instead of fast/CEF switch?
When a physical switchport/routed port has high usage, you can move the link to a higher capacity port, upgrade the port, bond links, etc. What exactly do you do when an SVI has high usage? I guess you could remove some servers from the VLAN, but that doesn't seem like a reasonable solution. What dictates the capacity of an SVI? The backplane of the switch?

However, I cant seem to find any recommended throughput guidence for the device? We could be looking at up to 80Mbps via the ethernet interface and I just dont know if the device will cope?
View 4 Replies View RelatedI have a Cisco 881 (without wifi model) connected to a 100Mb unmanaged switch and a cable modem with a 120Mb down, 10Mb up connection. When I connect the modem directly to my laptop, I can reach the 120Mb/s down and 10Mb/s upload speed. When I connect the modem to the 881, the max download is about 30Mb/s. Upstream 10Mb is no problem. I've been trying to change the duplex and speed settings on the FastEthernet4 interface, but this has only a worsening effect. I should be able to get about 100Mb/s (since switch is only 100) right?

We have multiple sites that have either fiber 20mb d/u or cable 50/10 d/u. Recently we have upgraded our head end router to a 2921 security based router and noticed that no matter if we are sending or receiving the most we can push is 1.6Mb. I would expect this number to be at least 8Mb for uploading and at least 18mb for downloading from other sites.I have included parts of my config and screen shots of bandwidth usage for troubleshooting.

View 3 Replies View RelatedWe've recently moved from using FiberChannel across an OC-48 between two data centers to GigabitEthernet. Data replication throughput has dropped from 700Mbps down to 45Mbps. The telco provider has demonstrated 1Gb throughput via UDP andTCP using T-Berts. However, when we connect two computers or servers, we do not get near the throughput performance.
View 1 Replies View RelatedThe issue was about Cisco ASA5510 Sec Plus.2 Interfaces, LAN and DMZ.Both 1000 FD, no interface errors like CRC or something similar.If I start a data transfer (like FTP) or a data stream test (like Netperf), from DMZ to INSIDE I get a theoughput.If I start the same from INSIDE to DMZ (same hosts), i get a troughput almost ten times slower.If i do the same using netperf in UDP (not TCP) I get the same in both directions.
View 9 Replies View Relatedwe have one OC-24 private line between our data centers. we are looking to get best throughput but we get max. avg throughput of 300Mbps with peaks of 800Mbps throughput. i.e. we transfered 2TB of data over this link and we got average throughput of 300Mbps with peaks of 800Mbps.
we should at least be getting 800Mbps throughput since we have OC-24 (1244Mbps) private line. we contacted our ISP but they said there isn't any problem in private line from ISP side. what can we do to increase average throughput?
Do some have some realistic performance numbers for a ASA 5505 on a mixed setup with local internet breakout and site to site vpn ( and don't tell me 150 mbps 3des throughput on a 100 mbps ethernet) - what can be expected in a live environment where we f.ex feed it with a 100 mbps internet connection - with a site to site vpn with f.ex 20 office workers running office on a remote terminalserver and mixed local internet breakout.

But we are getting not more than 4 Mbps download speed. We did open Tac case and as per Tac 2811 router is not for 30 Mbps.Can any suggest proper model. We need 2 FastEthernet/Gig and one serial port.
We have 15 small branches with Cisco 881w in every office, they use VPN site-to-site to vpn- concentrator on V yatta. I launched cacti monitoring of cisco 881's CPU's Errors, Traffics, Non-uni cast, Uni cast.

Is there an easy way to test the throughput speed of 2 powerline adapters? I want to know if they are underperforming so I want to rule out my router/internet in this test.
View 5 Replies View RelatedI recently bought a WRT160NL router. I have a 10/10 Mbps internet connection, but when I am connected via the router it only gives me ~2.5/1 Mbps speeds. Connecting my computer directly to the "wall" results in 10/10 Mbps speeds. I have tried connecting to the router both wireless and by wire, it makes no difference. The internal wired and wireless speeds are fine, as I have copied files over the internal switch and via the wireless network at relatively high speeds. I have not fiddled with any connection settings except creating a few permanent DHCP leases.

View 1 Replies View Relatedrecently we had some performance issues with C2811 which caused us to do some lab testing. For testing we used also C1812. The results were quite surprising for us, as the C1812 appeared to be more efficient than C2811. Below you can see the lab scenario and results.
1. Why C2811 is performing worse than C1812?
2. Is there any official Cisco reference stating what are the max VPN throughputs of certain platforms/models? (we consider migration to C2900 platform and would like to choose the right model)

as presented on the small diag:
All routers had enabled onboard hw VPN modules and SEC/K9 IOS ver. Configuration was very simple and beside encryption there were also GRE tunnels configured and EIGRP process for routing between "remote LANs". Part of conf responsible for encryption:

What is a backplane throughput of C3925-SPE100, I tried searching in datasheet but could not find
View 3 Replies View RelatedAny way to test throughput on a routed SG-300. I tried using iperf with netbook on VLAN1 to netbook on routed interface running @ 100mb. I was getting results as low as 40mb upto 200mb (sometimes even 2gb, I assumed these to be flukes). Since implementing it, the throughtput seems worse, I'm getting between 10 - 40mb of throughput. I have about 30 clients behind it routing across a 100mb leased link. I don't see why the SG300 shouldn't be able to do wire speed routing (upto 100 hosts). How to verify the expected throughput consistently?

View 2 Replies View RelatedAm looking at purchasing a router that is capable of serving a WAN bearer at up to 1Gbps. The 3945E has had good reviews as a high throughput router but the datasheets suggests performance of 350Mbps. It also states that additional performance can be ensured by adding SPE modules. Whether the 3945E could achieve up to 1Gbps with SPE modules?
If the 3945E can't achieve such performance, The key features I am after are:
IPV4 and IPV6 support
L2tpV3 support
BGP
IP SLA
1Gb Copper Connections on-board with capability of at least 4 Ports
