w3wp.exe

I have been caching a few more things on my asp.net web application in an attempt to speed things up. I am trying to figure out if I am running out of memory.

My webserver has 512mb of ram. A trend that I have noticed happening is major slowdowns at night when it seems to get busy and my CPU usage hits the roof.

I watched performance monitor as it happened.

I was using 182mb of ram, and it was showing only 13 available on the windows task manager and the CPU was chuggin along at very high usage (sitting at 100% + )

Then all of a sudden it drops to 165, and cpu usage seems to drop down to 30% and the site speeds up again. Over the next few minutes it climbs up to 197 then casually drops to 181.

Now the performance tab is showing 75mb free while its still using 180mb of ram. When I add up all the processes I do not come near 512, in fact not even 256.

My page file usuage is 365mb

If anyone can give me any tips to helping this slowdown stop it would be greatly appreciated. Or tell me what other info I can provide to help further, that would be great.

Thanks again

mike123Could it be something to do with garbage collection?

I am planning on adding 256 more RAM tonight, even tho I can't narrow it down to that.

Thanks for any ideas
