Re: BUG #15609: synchronous_commit=off insert performance regression with secondary indexes

Hi Peter,

That is unfortunate (both your results and the hash performance info).
We are still testing hash indexing and select/update/delete performance and
will keep that warning in mind.

I have replicated my setup by running the script by hand (see below).
Can you see anything in the test setup that seems to be wrong?

Thanks for all your feedback.

Cheers,

Paolo

------------------------------------
Notes:
Aside from the port number, all other settings are using default values,
and is only overwritten when we pass in -o on pg_ctl at startup.
The pgbench outputs are grep'ed and awk'ed to only show tps including
connections establishing.
Changed timing run for pgbench to only 10 secs. This was enough to show the
pattern and I didn't want to run the pgbenches again @ 20 mins per data
point.
Note how I am changing the insert sql and watch the pgbench patterns change
when sync commit is off/on and when the indexes are applied to bool or text
columns.
The data is still consistent with my initial results :(. If anyone can spot
where my tests could have gone wrong that would be very much appreciated.

Raw commandline output below.
