Hello!
After upgrade PostgreSQL from 8.0 to 8.1.4 a VACUUM FULL ANALYZE
process is much slower, from logs:
8.0
[13666][postgres][2006-10-06 01:13:38 CEST][1340121452] LOG: statement: VACUUM FULL ANALYZE;
[13666][postgres][2006-10-06 01:39:15 CEST][0] LOG: duration: 1536862.425 ms
8.1
[4535][postgres][2006-10-10 01:08:51 CEST][6144112] LOG: statement: VACUUM FULL ANALYZE;
[4535][postgres][2006-10-10 02:04:23 CEST][0] LOG: duration: 3332128.332 ms
Databases are equal.
I'm not using autovacuum.
Linux kernel is the same in two cases.
$uname -a
Linux zamczysko 2.6.13.4 #2 SMP Tue Oct 18 21:19:23 UTC 2005 x86_64 Dual_Core_AMD_Opteron(tm)_Processor_875 unknown PLD Linux
Why new PostgreSQL is slower?
