Hi Heikki, As requested earlier, I need some assistance from the Postgres side to identify any tool or testcase to calibrate the sync routine performance in Postgres. I see the below tools for benchmarking.
* Pgbench https://www.postgresql.org/docs/current/pgbench.html * Pg_test_fsync https://www.postgresql.org/docs/current/pgtestfsync.html * pg_test_timing https://www.postgresql.org/docs/current/pgtesttiming.html Please let me know, if these tools are fine or else ca you suggest us with any additional tools to run the benchmarking. > > Ok, if we don't need the assembler code at all, that's good. A patch to > > introduce AIX support should not change it for non-AIX powerpc systems > > though. That might be a good change, but would need to be justified > > separately, e.g. by some performance testing, and should be a separate > > patch. > > If you make no changes to s_lock.h at all, will it work?
