Hi, I currently have a vps instance with 6Gb’s of ram, I read about the performance gains of hhvm and decided to try it on one of my production sites, after turning on hhvm, I noticed some performance improvements but my memory usage has gone up to 1.5GB of ram as opposed to 300-500MB of ram I used to get before HHVM.
I looked around for performance tuning configurations and saw an article on github where facebook recommended turning on the RepoAuthoritative mode since it helps to pre-compile the source code into a bytecode repo. Ever since I enabled it my memory usage has gone up to 2.9GB’s of ram.
I’m not sure if this is how HHVM is supposed to behave with memory or I just have something wrong in my hhvm config. Also I’ve noticed
service php5-fpm status always has the
stop/waiting response even when I can see it running with
top , is that as a result of hhvm running simultaneously with php5-fpm as a fallback?
