[NTLUG:Discuss] LAMP Server Benchmarks?

[NTLUG]

LAMP as in Linux/Apache/MySQL/PHP...

This is a diverse group so I'm hoping someone might have some knowledge
on this...

I'm trying to figure out what size machine to get to support "X" number
of users.  The site is a few PHP type forms, and dynamic pages, mysql
queries to build parts, etc.  That being said, if I had a p3-500 512MB
ram, how many consecutive users would that machine support - with each
visit being a few minutes in length.

Obviously WebHosting companies would probably have the best information
as far as this goes, but I'm looking for any ballpark figures to start
with.

Also if anyone knows of any good bechmark apps/suites that might help
with this I would be interested in hearing about those as well.

thanks,
