Why has to be "porn" and not a "Wii game" for example? Any personal experience?

You don't say - what is your ISP connection bandwidth?
You can't have " nothing on the ISA server " and " the Websense plugin .. and
the Kaspersky AV plugin " at the same time.
Both of these components are very request- and content-driven (especially the
Krapersky component, which is scanning for malware/viruses/kitty porn).
If the perceived responsiveness without ISA is the same as through ISA, then
ISA itself isn't the problem.
What you need to do is start monitoring your logs for heavy traffic from your
internal users. It's entirely possible that one or more is compromised (or
downloading porn) and this is what is sucking up your bandwidth.

Hi all,
We have a single ISA Standard server with web proxy clients (around 200 of
them), and around 20 Exchange OWA/Outlook anywhere users connecting through the
ISA server.
There is nothing on the ISA server apart from ISA itself, the Websense plugin
(Websense components are on a different box), and the Kaspersky AV plugin.
Server is a PowerEdge 1850 with a single 3 GHZ Xeon processor, with 2GB of RAM.
RAM usage is slightly higher than that at around 2.7GB.
Incoming connections are fine for all the Exchange stuff, but outgoing web
requests are very slow. I believe the problem is due to a congested Internet
pipe, as I get similar speeds when not going through the ISA proxy, and the
traffic monitoring stats on the pipe suggest that the ISA server IP address on
the external interface is eating the bandwidth. However, I was wondering
whether there is any way of telling the throughput of the ISA box, or whether
the ISA box is responsible for the slowdown in any way? The directors need
this information before shelling out for a faster pipe.
Thanks.
Andrew.
