Unfortunately I couldn't figure out how to get gnuplot to do this. I ended up doing it in gnumeric. I'll look into fixing it the script up to be more automatic. Maybe look at gnuplot again. > I can run some tests on smaller Linux/Solaris systems to see if they don't > show > a regression, that was my main concern about this experiment. Heikki suggested some things to test for regressions. I'll look at that. What I'm more curious about and hoped I could get data from others is whether posix_fadvise(WILL_NEED) does anything useful on various versions of FreeBSD, OSX, etc. Afaict the syscall doesn't exist at all on Solaris though, which surprises me :( -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's RemoteDBA services! -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
