Re: running in a virtual environment

Good question. I hear about putting WAL/indexes/tables on separate spindles
and all that, but what if all IO is virtualized?
I would guess that IO and OS page cache would be the main issues here.
i haven't dared to put my db on a virtual box though, because i don't know
what happens inside of it.
