4 core Opteron performance

2006-10-21 Thread ke han
I realize this is a bit open-ended.  But I need some advice anyway as  
I need to make a final decision on using FreeBSD 6.1 on a production  
server.
I have a new Sun x4100 server.  2 x dual core Opterons with 8 GB  
RAM.  I need to run MySQL 5, a single threaded HTTP server, and a few  
other single threaded daemons.
This server will have lots of long living sockets for one of the  
single threaded servers.  Other than that, its not outside normal  
usage bounds.
I would like feedback on overall performance from anyone who has used  
FreeBSD 6.1 with hardware similar to this.  I'm not a guy who cares  
about getting the last 10% of performance out of a server.  I am  
happy to trade performance for maintainability and a little peace of  
mind.


btw, I'm not tried to start another FreeBSD has poor SMP flame-fest.

any thoughts?
 thanks, ke han

I have a dual opteron 2.0ghz (not dual core) with 4GB ram running  
6.1.  It ran a very busy mysql 4 server (feeding three other  
dedicated apache server machines), plus it runs a few FrontBase  
databases that are not so busy (low -- med low usage), and about 30  
instances of apache (ie, min of 30 jails, each running their own  
apache) and a couple of jails with roxen serving webpages, plus a  
bind daemon, a moderately busy exim mta, courier imap and pop  
daemons, and some other assorted stuff, like a bunch of java based  
WebObjects instance and some db stuff (like some low use mysql 4/5  
etc).  It rarely broke much of a heavy sweat in normal usage.  The  
super busy mysql 4 server is now gone and the machine rarely even  
sweats at all now (all the rest is still there).


I would google on x4100 and FreeBSD or search the archives for any  
machine-specific issues.  I kind of remember some issues with some  
sort of Sun servers.
