I have a customer complaining of slow response time BECAUSE of the content switch, which is load balancing web servers. Any idea of how to speed that up? Below is the config, Id be glad for any help.

I'd be very surprised if the content switch was slowing down access the webservers based on the config you have shown, I would look for other potential network issues - duplex settings maybe on the CSS ?
There is an issue with the CSS when uploading through the CSS it has a 10-12K window size (although this has been increased to about 40K in Version 8 of the WebNS software)

thanks for the response. How would I go about checking the window size out, and if needed, how would I go about increasing that to version 8? Im not real familiar with it. Any help would be appreciated.

Well, this problem causes slow upload behaviour through the CSS, so firstly, is this the problem your customers face ? If not then you have another issues.
If you have access to CCO you can download the images from cisco.com software centre. The upgrade procedure is in the release notes.
In my company I can download images from Cisco but not sure how you get your images for routers/switches/ other devices.
cheers,
Mike

Customer complains of slow ftp speed to their webservers. This does sound like what you mention to me. Ill take a look at that first, thanks. Would this be the same as an image upgrade?

I would first capture sniffer traces of a client accessing the webserver directly and then the same client accessing the same page through the CSS.
Compare the 2 traces and how long it takes to get the response.
Sometimes people *feel* that it is slower.
But data proves it's not.

Is there a way to set the interface to full duplex on the content switch?
02-22-2007 08:22 AM
by default the CSS is in auto mode, so it should negotiate with the switch full duplex.
Do a 'sho phy' to verify your current settings.
If you're not in full-duplex, you can force it with the command
interface 3/1
phy 100Mbits-FD

Yeah, just did the "phy" command. Very different that what I have seen on a router or switch. Thanks, that did fix the issue.

also, if you copied this config directly, please note a misspell of a service name in your content config:
sewrver280
