Hello.
I'm trying to restore my database from dump in several parrallel processes, but restore process works too slow.
Number of rows about 100 000 000,
RAM: 8192M
CPU: Ultra Sparc 3
Number of CPU: 4
OS: SunOS sun 5.8
RDBMS: PostgreSQL 8.0
==================== prstat info ====================

124 postgres 1520M 1306M 16% 0:03.05 5.0%
How to encrease postgresql speed? Why postgres took only 5.0% of CPU time?
