Performance boost for LAMP stack
This weekend I got around to benchmarking conshell.net and my own website using apachebench (ab). For some time I suspected conshell as having sluggish performance and ab showed it was only able to serve three requests per second for the home page. So I added varnish and APC to the mix, the performance increases 3x. I recommend anyone with a sluggish LAMP server look into these two options. Here are my #s from ab.
