Urgent Performance Help

Hi, I run a small IIS 5.0 webserver out of my basement on my cable
connection (60K/sec upload). The specs are:

Dual P3 800 CPU's
512MB RDRAM
16GB SCSI HD

Normally my site gets around 400 hits a day, but something happened
today that caused this number to jump dramatically. I'm now getting 400
hits every 10 minutes. Because of this, people are having problems
connecting to the website. The message "Connecting to www.blahblah.com"
comes up and nothing happens. If you keep pressing reload over and
over, eventually the page will load up. I am able to log into my other
computers on my home network, so I'm pretty sure it's not a bandwidth
issue. I've changed some IIS settings to allow it to use maximum memory
and have this website exist in its own space.

These measures haven't help at all, and I need a bit of advice. Again,
I'm just serving a very simple text only HTML page and my server is
having big problems handling the traffic.

Thanks for any suggestions,

Gary.

Have you tried testing the site locally on the local network when the
problem occurs to see if IIS is serving the pages?

Might start by asking why you're getting so much extra traffic. Could
be all of them are malformed headers and you're suffering a denial of
service. Check your IIS logs and your firewall logs for clues.

I would suggest that your outbound bandwidth (I assume that's 60 kilobytes /
second) is being completely saturated. That's only 10-12 remote users on
dial-up, and less if they are on broadband.

You can probably connect fine across the local area network, because the
server is not under any load and your local area network connection
(probably 10 or 100 megabits) is not saturated at all. With the server that
you have, the server itself is not going to be unduly burdened - you should
be able to service hundreds of requests a second with the hardware you have
(if the pages are simple HTML, or simple ASP pages).

Cheers
