Well, I thought -Xms means that. An untuned VM is not expected to hit the -Xmx limit. At least this is what I see in practice, and to me this is the distinction expressed between the -Xmx and -Xms flags. I am very sorry, "-Xmx" was a typo, or perhaps a thinko. In my original posting -- which was trimmed -- I said

Oops, sorry.

It makes more sense to allocate all the -Xms size immediately. and I thought you were disagreeing with me, but:

I tried to explain that, currently, the whole heap is reserved. I think we agree that it makes sense to reserve just the -Xms portion, and leave the rest at PROT_NONE (or whatever mechanism the kernel developers recommend).
