So, it's better suited for databases, such as MySQL. XFS-1.0 is already available for Linux (kernel 2.4), and it's fully stable.

What's the best os?
Hi group, I am putting together a new web server to serve our new web site. We expect a-lot of traffic on this site, so we have purchased a HP LH4 quad xeon 550 2mb cache server. The site will use the mysql database to hold about 125,000 squ's with descriptions, and notes for each squ. The web surfers will be searching through the database frequently. My question is, what is the best OS for a heavy usage, multi-processor mysql database driven web site. We could use almost anything, but we would prefer to use a free OS such as freebsd or Linux based OS. Any input would be greatly appreciated!!

We could use almost anything, but we would prefer to use a free OS such as freebsd or Linux based OS. This is treading dangerously close to religious war.. I would wager that the performance difference between a Linux install and a FreeBSD install would be so small that it would be more valuable to make the decision based on a different criteria. Perhaps instead of performance, you can weigh whether it on which platform your developers are most comfortable with, or have the most experience in.. There are exceptions of course, such as one OS having better drivers for your hardware than another, but generally, it's hard to place one as being better than the other when the choices are FreeBSD or Linux. Linux vs say, Solaris on the other hand is much different. Especially where MySQL or Apache are concerned.

FreeBSD won't let you take full advantage of both CPUs the way other OSes will. One thing that's not entirely clear, though, is whether your server is a database server only. Or do you plan on running Apache on it as well? If it's not a dedicated DB server, the multi-processor issue will become less important. Jeremy -- Jeremy D.
