No bandwidth issue here, just the server getting killed. It depends on the application. For something with many reads and fewer writes like a forum or basic, if busy, e-commerce you'd consider setting up MySQL replication with one master for WRITE operations and multiple slaves for SELECT operations. For something with a high write/read ratio such as eBay, that would be a wildly-unsuitable solution. Your best bet is to ask the MySQL folks, honestly, since it's unlikely that anything in PHP is going to be the answer to this one. If you have RAM to spare, you could: Configure /etc/my.cnf to have N + X connections Use http://php.net/mysql_pconnect N would be the number of Apache Max children X would be a few spare connections so that, if, say, you NEED to use shell 'mysql' monitor to DO something, the fact that ALL N connections are taken by Apache, won't lock you out. There are significant RAM issues with pconnect, as well as some bugs in various versions of PHP/MySQL that make this answer a no-go. Tread carefully. But it's at least an on-topic answer, even if an incomplete and maybe downright bad answer. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] PHP and mySQL getting smashed...
I have a site that is getting 30K+ traffic daily and it is smashing mySQL - any ideas on what to do to make the mysql connections more efficient, or anything in general. No bandwidth issue here, just the server getting killed. Thanks

No bandwidth issue here, just the server getting killed. ...I may be wrong but using persistent connections (mysql_pconnect) may help.

perhaps post some code so we can look at how you doing your queries...

Even the fastest server in the world would wilt under a slashdotting, if it had to do a dozen big queries for every page display. Meanwhile a Pentium3 with a decent network can serve hundreds of requests a second of a few static pages.
