Might be getting close to the limit, but I don't see evidence
that the system is at the limit (i.e. that it's memory-starved).
The swap used is very low; if the system were swapping, it
would probably be higher.

So yeah, more memory would help, since it always does, but
lack of memory doesn't appear to be the primary problem.

Of course, without seeing stats of how many messages are in a
batch and how long that batch takes, it's difficult to tell
what the problem is.  Is MS using 60 seconds of CPU time
for one message?  Or is that 60 seconds for a whole bunch
of messages?  If the former, there is a significant problem
not related to memory.
