What does Mod_lsapi PRO give you? (included with CloudLinux OS)
Up to 10% better performance
mod_lsapi PRO connection pooling improves performance by up to 10% compared with the standard mod_lsapi shipped with cPanel. CloudLinux OS eliminates connection setup delay by reusing connections previously established between Apache web server and LSAPI.
Faster startup after Apache restarts
Opcode caches stay hot between Apache restarts, because mod_lsapi PRO doesn't flush them.
Fast Time To First Byte (TTFB), with low memory footprints in multi-user environments
mod_lsapi PRO uses process checkpointing (CRIU) to save the state of PHP processes. It avoids using slow, in-memory persistence, delivering extreme TTFB ratings and a minimal memory footprint.
*Note, that Mod_lsapi is included free with cPanel, but it does not include any other CloudLinux OS features.
