My situation is this. We have a semi-production server where we pre-process data and then upload the finished data to our production servers. We need the fastest possible write performance. Having the DB go corrupt due to power loss/OS crash is acceptable because we can always restore from last night and re-run everything that was done since then.
I already have fsync off. Short of buying more hardware -- which I will probably do anyways once I figure out whether I need more CPU, memory or disk -- what else can I do to max out the speed? Operation mix is about 50% select, 40% insert, 10% update.
Mount WAL on RAM disk. WAL is most often hit area for heavy updates/inserts. If you spped that up, things should be pretty faster.
A non-tried advice though. Given that you can afford a crash, I would say it is worth a try..
