Wonder why the move from 50% to 10% as a default for RAM caching???

For unihome cache servers I have seen recommendations of 80-90% for ISA 2000...is this still valid for ISA 2004???

Hi Jason,

I was surprized to see such a low value too. In general, esp. for a dedicated ISA caching firewall, I would dedicate as much RAM as possible by monitoring the pages/sec counter. I keep bumping up the RAM percentage used for caching until I get too many pages. Seems to provide the best performance overall for firewall, OS and caching features.

HTH,
Tom

Hi Jason,

Nope. I've got mine set to 60% and almost no pagefile hits. The cache really seems faster to me now, esp. the transparent proxying.

Thanks!
Tom
