 Hello!  I'm in the process of upgrading my Linux-server (currently a

 experience (good or bad) with a dual Athlon system with Linux running
 MySQL 3.23.x, and maybe Apache under HEAVY load?

Our kernel people love them - Athlon goodness, no VIA chipset. Good
performance, good stability.

 Since the Athlon MP's haven't been around for very long, I'm a bit
 concerned about the stability under heavy load on the 2.4 kernel...

Ve've supported it since RHL 7.1 (which was released before the Athlon
MP, if memory serves :).

 So please, if you have a success- or disaster-story I'd like to know!
 :) I'm also very interested in what mainboard you are using for the
 Athlons, and what Linux-kernel version you're running...

Red Hat Linux, various release and test versions (kernel and
surrounding OS).

Well, I don't have anything yet, but I've got a server in the mail
coming to me that is a dual Athlon MP 1900+. I'll be getting it either
today, or tomorrow with any luck, and I'll let you know how things go.

Gonna be running SuSE 7.3, PHP, MySQL, Apache, BIND9 and various other
packages on it. Oh, and SETI@Home, to burn in the processors. ;)

Note that the Via kt266a (_not_ SMP chipset) is quite good these days.

If I was building a dual-processor machine, there's no doubt I'd go for an 
Athlon system at the moment.  For a quad-processor machine, I'd look much 
more closely at the P3 Xeon chip (the P4 Xeon has no 4-processor motherboards 
afaik).

ObMySQL:  Make sure you are CPU-limited before considering SMP machines.  If 
you are hard drive limited, you aren't likely to see any advantage going for 
more CPUs.  SELECT MySQL PostGreSQL, UPDATE, INSERT, terrorism, world trade 
centre, replication, etc.
