It would seem we're experiencing somthing similiar with our scratch
volume (JFS mounted with noatime).

Which files/directories do you keep on "scratch" volume ?

All postgres files or just some (WAL, tmp) ?

No Postgres files are kept in scratch only the files being loaded into the database via COPY or lo_import.

then the speedup does not make any sense !

We do a lot of preprocessing before the data gets loaded. It's that process that experiences the hiccups I mentioned.
