Re: [PHP-DB] mysql -- Commercial DBs, When will I need to upgrade?
Some people in the APC mailing list have said that mysql blows up at around 200-300 queries a second. http://lists.communityconnect.com/pipermail/apc-cache/2001-April/000611.html Phil Jackson [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: [PHP-DB] mysql -- Commercial DBs, When will I need to upgrade?
Your DB needs sound more hardware intensive than anything. Your queries sound simple and I would bet you would never need to use anything but mysql. Also keep in mind that mysql/php/apache etc run on more than just PC's. There is some serious hardware out there that can handle unbelieveable amounts of trafficof course non of it is intel based :) If an Intel box can no longer handle the load, you can split your servers so you have one running a web server and another handling the DB, or simply move to some real hardware. (ie HP/Sun/IBM unix boxes). Larry H. Doug Schasteen wrote: I've been programming PHP w/ mysql for almost 2 years now for my company. We develop online testing and surveying software.

If anyone has had some experience with upgrading as your operations grow, I'd appreciate if you could answer ANY of the following questions: Did you say M$.. yuck.. if you think you need something else then MySQL you could take a look at PostgreSQL.. It's good, it's free and it doesn't have M$ written all over it :-) The subject sounds like commercial databases are better then OpenSource.. I don't think that's treu. You could find great solutions in OpenSource.. Like MySQL.. PostgreSQL and others.. I even know quite a few people on several lists who kicked off commercial products and started using opensource.. for various reasons. If you look at the specs.. you will see MySQL performs very good.. also with large databases. Having your own dedicated server will help you to get better performing websites.. Memory.. the more.. the better.. you can have to little but never to much of it.. If you're currently experiencing performance problems I would assume a dedicated server might help.. Bye, B.
