Hi there! I just want to let you know that I have the eaccelerator php cache at drupaldevs.org. You can enable it for your site by setting php_flag eaccelerator.enable 1 and php_flag eaccelerator.optimizer 1 in your .htaccess file. I did some tests and found my test setup to have a reduced page execution time that went from about 240ms to 130~160ms. Memory usage was also reduced. I am not sure if the memory consumption numbers are accurate. They were retrieved from xdebug and that might interfere with the eaccelerator extension. Cheers, Gerhard
