Tom, sure I will append the basho_bench config. This is with bitcask.
I did some tests with leveldb and the performance was also very good,
but not as good as bitcask obviously. I will try benchmarking for a
few hours as you suggested.
I am using this in a production environment (for a multiplayer game
with just about zero $ budget to work with). I know with bitcask I
might run up against not-enough-ram for the keyspace so I will have to
keep an eye on things. But I would be able to upgrade the vms to the
larger size with a simple reboot of each node in the cluster.
