Premature optimization and > all that. You're thinking about 2 processes, with 9 processes I would expect the kernel to be able to scedule things across multiple CPUs just fine. > I'd probably pick the database that worked better > for me (Postgres, > Firebird, whatever), and just move the AOLserver d > to a Linux box > later if it turned out I really needed AOLserver to > use that second > cpu, and FreeBSD was getting in the way of that. Well that's why I was trying to get a handle on just how well Firebird was supported by that ancient driver. > Actually, you could always just run two > load-balancing AOLserver > processses on the one FreeBSD box, exactly the same > way some high > traffic sites run multiple AOLservers on multiple > Linux boxes.

There *is* a difference there- try to find me a single-cpu machine with hot-swappable drives and dual redundant power supplies. They don't really exist- those capabilities come on higher-end 2/4/8-proc machines. I guess another option would be a virtual-server model with multiple instances of the OS running on that front end. ===== -- live- http://www.thedenofsin.org/ to- AIM: IMFDUP _-jupiter accepts your offer-_ -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list, simply send an email to <[EMAIL PROTECTED]> with the body of "SIGNOFF AOLSERVER" in the email message.
