Hello - I would try the following: 1. Convert to PHP4 since it is substantially faster than PHP3 2. Run the latest Apache (1.3.x) and MySQL (3.23.x). 3. On FreeBSD, look into the MAXUSERS and NMBCLUSTERS options in the kernel. 4. Possibly try caching with Apache 5. Tweak MySQL. I would not run Apache 2.0 at this time, since it's still beta. Plus, I may be wrong, but I don't like PHP supports it yet. Just my .02 - David On Mon, 2 Jul 2001 15:13:24 +0200 "Nadir@Attractive" <nadir@attractive.com> wrote: > Hello all, > > I hope this is the first time anyone is asking such a question, but I > couldn't find any help in the archives. > > We have a FreeBSD 4.2-STABLE server running mainly Apache, PHP and > MySQL.
