For a read only comparison (which was run using the simple protocol), using identical settings to the previous master run, but with the PGPROC split patch: m32 tps = 201738.209348 (including connections establishing) p32 tps = 201620.966988 (including connections establishing)
m128 tps = 352159.631878 (including connections establishing) p128 tps = 363998.703900 (including connections establishing) Clearly a win at 128 clients; not at 32. For updates: sm32 tps = 27392.393850 (including connections establishing) sp32 tps = 27995.784333 (including connections establishing) sm128 tps = 22261.902571 (including connections establishing) sp128 tps = 23690.408272 (including connections establishing) pm32 tps = 34983.352396 (including connections establishing) pp32 tps = 36076.373389 (including connections establishing) pm128 tps = 24164.441954 (including connections establishing) pp128 tps = 27070.824588 (including connections establishing) That's a pretty decisive win all around. -Kevin -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
