Interesting. On Win64 I've found it to be consistently faster. Also, the
cmem unit changed to call into a copy of Jemalloc.dll (i.e. je_malloc
instead of malloc and such), something I've experimented with, is WAY
faster.

I didn't mean that it doesn't *care* about being fast, but more that it
will not necessarily use more memory in all cases that it might result in a
speed gain, and generally is more concerned with a "balanced" approach,
which is what I've always heard to be the case. Is that really not true at
all?
