We've done some benchmarking of Magento on Litespeed/PHP-LS against Apache/PHP-FPM using magespeedtest.com and found that Apache/PHP-FPM is consistently a small but non-negligble amount faster. We already have a large LSWS install base but are considering switching to Apache/PHP-FPM for the performance increase. Is there anything we can do to improve Litespeed/PHP-LS performance? Our standard LSWS config is here: http://pastebin.com/amTTyhHQ
