Litespeed, LSAPI ProcessGroup and CageFS work amazing on single core Litespeed web server. If we use 2+ Litespeed cores, actually each process will spawn his own PHP process groups and they do not share the same memory used for OPcache or APCu in-memory cache. This is a huge problem, not able to use a multi-core web server in 2018. Litespeed teams say they do not have a solution right now for CageFS but since you collaborate with them, it will be nice to make this work.
