They have a standard (free) version and a pro (paid) version that should perform much better than Apache and PHP.

RE: question on hosting and memory
David, First no host should be running anything less than dual 2.x Xeons and 1GB of RAM. Thats a minimum. Add a large swap of about 4GB. Then tailor your 1.3 so it only compiles with the components necessary. Basic core, PHP, Frontpage, Python as DSO whenever possible. And your PHP should only be compiled with what you actually expect to use. Our httpd's are using about 10MB each with PHP loaded. Then fine tune your httpd.conf timeouts so that those idle processes don't stick around too long. Then tune your kernel settings a bit. I use these in sysctl.conf and came about them through trial and error mostly. Of course this means that somebody on the list here may disagree with them but they work well and help keep the processes in line. kern.ipc.somaxconn=1024 kern.maxfiles=2 kern.maxproc=12328 kern.maxprocperuid=11084 kern.ipc.nmbclusters=32768 net.inet.tcp.recvspace=32768 Of course you will need to fine tune other full time applications on the machine to use as little resources as possible themselves. This includes your SMTP server, Pop3 server, etc. The more you can fine tune the faster the machine can do its business and move on to the next task. Hope it helps, Wil Hatfield HyperConX -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of David Banning Sent: Wednesday, August 03, 2005 10:27 PM To: [EMAIL PROTECTED] Subject: question on hosting and memory I am running apache 1.3 with php and I find when that for each person who visits the site, an additional 29 meg is consumed of my measly 512M.
