Just a little followup to this, I tried 9.4.0 and was seeing about the
same amount of performance as 9.3.2 . However this seemed the vary between
3,000 and 25,000 queries/second depending very much on what sort of queries I was
sending to it. I need to do a little more testing to work out what is
happening.

I'll hopefully post some more if/when things make more sense.
