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.

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.


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

any thoughts?
 thanks, ke han
