optimze for a mysql server - my.cnf

[kean galileo]

hi I'm new here and new with using this database. have little a backround with ms sql.
since I moved my site to a php on I have stared using mysql.

I have a site with 2 servers one is for the mysql database and one for files.
the server of the my sql is a dual XNON 2GB RAM very powerfull.
and it sould deal with a traffic of 15000 a day. and about 2000pepole /hour at heavy hours:

but since I belive the configurtion of my.cnf is bad I guess it has heavey loading time and sometimes not reasponding.
and maybe its a PHP.ini or httpd.conf problem so if you thing my my.cnf is good and you think of a good reason please write it here anyway.

THIS IS MY CURRENT MY.cnf
