Hi,
     I am running FreeBSD 5.4 on SunFire v20 on single
hard disk 73 GB...

I googled down some links regarding increasing IO
performance.  It said increase vfs.read_max from 8 to
16. I have done that, but cant justify any
improvement, as I am running mailserver(spam checker).
 Should I revert to 8 or use 16.

Have any one tried or is it recommended.

Also, how do I enable hyperthearding, does it improve
performance...

Cheers,
Deepak Naidu
