I have been using eAccelerator (Fedora Extras) for some time now. I have been toying with APC on a test machine (with httpd 2.20 and PHP 5.1.1). I am wondering if anyone has tried it on a production server and might have some clue about a performance comparison to EA? -- Our DNSRBL - Eliminate Spam: http://www.TQMcube.com/spam_trap.php Multi-RBL Check: http://www.TQMcube.com/rblcheck.php Zombie Graphs: http://www.TQMcube.com/zombies.php GeoGraphics: http://www.TQMcube.com/origins.php
