[Vtigercrm-developers] Input on optizing VT performance?

[Alan Bell]

I found HHVM to be fast, but not much faster than using an opcode cache, 
which I think is simpler to set up and easier to keep updated.

that speeds up PHP processing quite a lot, then you are probably 
database bound and need to look at indexing - oh and stick the database 
on an SSD rather than rotating disk and it will go quite a bit faster.
