the 2948 and 4006 use the same software and are almost the same hardware and have about 4 Gigs on the backplane. Your etherchannel should give you 200Ms between chassis.


Run a ping from one switch to the other to see if the channel is over used (or use an NMS). If the link is over used add another link to the channel...

If the response times are good, you have a problem on your end devices. run a ping between these systems to check response times.

If the times are marginally different to the switch response times, you know the problem is related to end device. If the times are the same, start pinging from each machine to each machine to isolate the latency.
