Apart from being better options like lighthttpd for handling high traffic, 50 requests/sec is VERY low for ANY web server. If you're using Apache and you're not able to handle 50 requests/sec then you got a very bad configured Apache installation (or a very low end server)
If you're using MySQL < 5.1 to store the DLRs on InnoDB tables which have an auto increment column it can really suck, since auto increments on MySQL < 5.1 are very resource consuming and produce locking. In theory MySQL 5.1 corrects this problem. Hope this helps. Regards 2009/7/12 Nikos Balkanas <nbalka...@gmail.com>: > Hi, > > 50 urls/s is very small.
