http://php-accelerator.co.uk/ 可以下載，是zend的強(qiáng)勁對手。是免費(fèi)的。我已經(jīng)在用啦。效果還不錯。修改 php.ini 加上：zend_extension = /usr/local/lib/php_accelerator_1.3.3r2.sophpa = onphpa.tweaks = onphpa.cache_dir = /tmpphpa.file_perms = 400phpa.cache_file_prune_period = 1hphpa.cache_file_ttl = 1dphpa.shm_size = 10phpa.shm_key = 0xc0deb00phpa.shm_perms = 666phpa.shm_user = nobodyphpa.shm_group = nobodyphpa.shm_release_at_exit = onphpa.shm_stats_check_period = 5mphpa.shm_ttl = 12hphpa.shm_max_processes = 512phpa.shm_lock_threshold0 = 10

apachectl graceful 就能用啦。具體參數(shù)看它的文檔。
