I have a question:

Our server: 4GB RAM, CPU Intel Pentium (R) III Xeon (4CPU) 2.7Ghz. Winserver 2k3, MSSQL Server 2k8. And there are about 100 active website, all the DNN.

But servers are overloaded:
- CPU usage: 80-90% (sqlservr: 1.3GB, w3wp: 600MB ...)
- PF usage: 08.04 BG.

DNN setting:
- Cache method: on page.
- Cache Module Provider: File
- Perfomation: Heavy
- Compress: gzip.

I created about 10 Pool and a Pool default, every pool is 10 site, except default Pool is 50 site.

The Pool I created just like default Pool. (I'm not using Cpanel, Plesk...). And I have not run the SQL Cron Jobs.
Can you advise me:
- Each site create a Pool or a Pool assign more site, the Pool have setting anything special (Recycle worker, Reques quee limit, shutdown worker ...)?
- How to running Cron Jobs, schedule or automatic...?

Thanks a lot.
