my two cents. * Caution: consult with support before making changes.

We have seen very significant benefit by increasing the allocated host memory. So much that 3 years back, we pushed for a DB change to be included in new software versions instead of the old grub based change. The default linux alloc is way too low. It however depends on what platform and software version you are running. If you are running redundant 3600's for eg, you can allocate like 2Gigs to your host. Very very simple change.
