Of course, with only 32 - 200 MB of heap, almost anything will collect
pretty quickly!

If you are only storing a little bit of data (coordination, basically) then
a small heap might work fine.  Turn on gc logging and read what you get.  If
that is ok even with high load, then you should be fine.

One application where I saw a need for memory was when we stored user
sessions in ZK.
