The ram increase from 4-6GB can have little or large impact depending on your mysql database backend.
LiteSpeed is extremely ram frugal so memory is never an issue with LiteSpeed. It will run just as well with 512MB of ram versus 6GB.
Your database however, will/might, love the increase in ram to cache data and indices.
We do recommend installing 64bit os as mysql will benefit. Tests have shown that mysql 64bit will out-perform the 32bit counterpart. LiteSpeed will run well regardless of 32 or 64bit.
