We have ISA running on a 512Mb of RAM 2000 Server.
It is a cache server. It is pointed to a webserver from which it caches the pages (duh). For some reason the first time the info is cached, it is quite slow for the user who is downloading the info (there is quite a bit of stuff being downloaded – 5 to 10 Mb). On the second go around, it quite fast. Example:
When I choose to pull the info from the webserver itself (no caching) – it is fast!!!. Then, I try to access the same info from the cache ISA server – it slows down by about half. Then, I try to access the info from the cache ISA server again – and now it is just as fast as from the webserver itself. I have tracert’d and know for a fact that both are on the same subnet and talk to each other on the same subnet. So, i do not think that the routing has anything to do with this. Has anyone seen something like this? I understand the first time the info is not present on the cache server, but should it not just pass it along and then write it locally from memory? Just can’t figure out why it is so slow the first time around. Please help. Thanks in advance.
