Server Load Balance on 6509

Cisco gurus:

I configed slb on two 6509s (native IOS, version 12.1(12c)E5). The performance is disappointing. The traffic to load balaced servers is about 4M/s. Previously, cpu load was less than 5%, now it's 30%. sh run sometimes takes 10 minutes to show up. A lot of messages like below come up. Our hardware (SUP1A, MSFC2 and PFC)dictates that IOS 12.1(12c)E5 may be the highest version that we can run.

I can only find one technical tip regarding SLB on 6500, and it's quite basic. Seems not too many people use this feature.

I post this to ccie-lab@groupstudy.com, and one guy replied that he is running almost identical config with Sup2, and he has no problem at all.

Can someone shed some light?

Thanks,

Weidong

Please re-post your questions to "LAN, Switching and Routing" under "Network Infrastructure." You will find more LAN switching expertise there. This section is mainly for questions involving SNA.
