Hi,

After outgrowing our previous dedicated server we plumped for a new Dell PE1950 with dual Xeon 5160s, 4Gb RAM and 15K SAS drives.

The server consists of the following...

Ubuntu 6.10 (2.6.17-10-generic #2 SMP Tue Dec 5 21:16:35 UTC 2006 x86_64)
Lighttpd (1.4.13)
PHP w/fastcgi (PHP 5.1.6 with XCache v1.2.0)
MySQL (5.0.24a)

I'm pretty happy with the way the box runs, however it seems despite having "memory_limit = 32M" set in my PHP.INI we're still hiting the limit during certain search conditions. On the previous box it ran fine with it set to 8 or 16M but that was back when we were running Apache :confused:.

VB is version 3.6.5.

If you need any more details please let me know.

A memory limit of 32MB really isn't that high. I've got a couple sites running at 128MB in order to keep the search from returning a white page. It really all depends on how large your DB is and how many results are returned.

Hi Jason,

Thanks for your input, I was worried about pushing the limit too high but it's obviously not even close.

The database is around 900mb and has the following stats.

How is Ubuntu working as a server operating system?

I'm very happy with it, boots much much quicker than the other distros I've tried too.

PHP 5.2 changed the memory accounting subsystem so it SEEMS like PHP 5.2.x actually uses more memory than 5.1 and earlier (which is why the default was raised from 8M to 16M).

That said, if you monitor the process size, it really doesn't and it's been my experience that 5.2 performs better then 5.1. I'd agree, try upgrading.
