I would suggest a lower -Xms and no -XX:PermSize (causing the starting
size to be the default, 64MB for the 32-bit VM). The initial sizes don't
need to be too large since some people may have less memory and/or small
workspaces. It's just important to set a reasonable maximum to avoid
OOMs (of the heap or permanent generation). Also, it's worth considering
that the 64-bit version needs more memory.
