I have two dell server 2950-III dual quad-core processors
3.0Ghz with 8GB RAM and 1TB SATA drive. Dell_1 has an
ip address of 192.168.1.10/24 Dell_2 has an ip address
of 192.168.1.20/24. Both of the dell is connected to
a Cisco 2960 Catalyst switch copper Gig. I am running
Redhat Linux ES 3 on these servers. I hard code the
interface to 1000/full
When I perform FTP between the servers, I can get about
800Mbps throughput. That's the good part.
Now, I have a Cisco 2621 (64RAM/16F) I connect both
F0/0 and F0/1 to the catalyst 2960. The router is
running IOS version 12.3(24). I set both the interface
of the router and the catalyst to 100 full-duplex.
I give F0/0 192.168.1.1/24, F0/1 192.168.2.1/24. I
give Dell_2 192.168.2.10/24 with the gateway to
be 192.168.2.1. Dell_1's default gateway is 192.168.1.1.
My FTP transfer is peaking out at 5Mbps between
Dell_1 and Dell_2 across the 2621. The CPU on the Cisco
2621 peaks at 99% cpu utilization. I see no
errors on both the catalyst switchports and on the router
interfaces. I thought I could get much better on the
Cisco 2621 than 5Mbps throughput. With
either SecureFTP (sFTP) or SecureCopy (scp), the through put drops to 2Mbps.
In other words, it gets worse.
Anyone know what the throughput for Cisco 2621 router?
IOS on the router is c2600-ik9o3s3-mz.123-24a.bin.
