Hi Dmytrii,

just as short idea, put "fsync = off" in your postgres.conf. That turns off that after a commit data is forcilby written to disk - if the database crashes there might be dataloss.

Thanks. So far I tried:

fsync = off
full_page_writes = off

It seems it got a *little* faster (down to ~65 seconds from ~76) but is till too far from my target of ~34 secs.
