Question

I’m currently using session variables as a cache to cut down the calls to the database.

I’m wondering at about how many concurrent users does this stop working at? 1,000, 10,000 ….100,000??? Also will iis start flaking out at a certain load? And are there any alternatives?

I know it depends on how much data I’m storing per user, but I want to hear from other peoples experiences.

I do have it setup so that when the code tries to access a timed out session that it reloads from the database.

I’m currently using iis6 but I could easily use iis7 if it handles sessions better.

Edit: Yes I’m using application variables for non user specific data.

You should probably be looking at Memcached if you’re getting to this point.
