Dear List,
I have been having a bit of a play with using COPY to load a reasonably large
table - 3 million rows ~ 57000 8K pages ("fact0" for those of you that have
suffered these postings previously).
I decided to compare 7.1.2 and current (7.2.dev 29/0701)sources on a number of
different platforms.
The results show a definite improvement for the current sources on all tested
platforms :
Linux 2.4( Intel 266Mhz ) 7.1.2 9m30s
.......................... 7.2.dev 7m30s
Solaris 2.8( Sparc 2x450Mhz) 7.1.2 9m
.......................... 7.2.dev 7m
Tru64 5.0( Alpha 2x500Mhz) 7.1.2 6m
......................... 7.2.dev 4m15s
The platform results are quite interesting themselves - surprisingly good
performance on the little Pc...
The Alpha is a 2 year old 910...*not too sure about Alpha model numbers*...
The Sparc is a new E220
Postgresql was compiled with the native compiler on each platform. All
databases had fsync=true,shared_buffers=4000,wal_files=10 and wal_buffers=20
regards
Mark
