Thanks. I will try with a more sensible value of wal_buffers.. I was
hoping to keep more in memory and therefore reduce the frequency of disk
IOs..
Any suggestions for good monitoring software for linux?

It's pretty easy to drive your system into swap with such a large
value for work_mem - you'd better monitor that carefully.
The default value for wal_buffers is 64kB. I can't imagine why you'd
need to increase that by four orders of magnitude. I'm not sure
whether it will cause you a problem or not, but you're allocating
quite a lot of shared memory that way that you might not really need.
