optimized MYSQL config?? (db running slow)
 

Awhile back i posted that my MYSQL was running super slow. Someone posted a MYSQL config file that really tweaked my MYSQL nice, allowing more connections, etc.... but i recently updated my server and I think because of that I lost my tweaked MYSQL config file... ... and I cannot find that post I made here from back in the day..

Does anyone have one they can post?

if you can't find it here or no one knows, take a peek at the vbulletin forums, there is a guy there that can really tweak the shit out of the my.cnf and httpd etc..

having trouble locating a good one...

my serv is a p4 2.2ghz with 1gig ram.

I ran an extended status mysql command and it fed me this:

nevermind. I increased the max connects by 1k and it seems to be running a lot better

Do you have very long connections coursed by large file downloads?
Otherwise 1000 connections seems a lot as you don't have that many queries

Absolutely turn on the query cache
and log long/slow queries

The cache can speed up complex queries requiring multiple connections amazingly...I've one query that w/o the cache takes 35 secs (2.5million entries), w/ the cache is immediate.
