Hi Markus,
As said, our environment really was a read-mostly one. So we didn't do
much inserts/updates and thus spent no time tuning those values and left
them as default settings.
Best regards,
Arjen

It was the 8core version with 16GB memory... but actually that's just
overkill, the active portions of the database easily fits in 8GB and a
test on another machine with just 2GB didn't even show that much
improvements when going to 7GB (6x1G, 2x 512M), it was mostly in the
range of 10% improvement or less.
I'd be interested in the commit_siblings and commit_delay settings,
tuning them could give a high increase on throughput for highly
concurrent insert/update workloads, at the cost of latency (and thus
worse results for low concurrency situations).
Different fsync method settings can also make a difference (I presume
that syncing was enabled).
HTH,
Markus
