Hello everyone,
in a substantial multi location development project we are using PG to create a large information system. After
havingloaded data in the order of one million records a vaccum took 50h of CPU time on a 350MHz PII (RedHat 5.2, pg
6.4.2).There were no deletes or anyting like that.
I made a test database when I was deciding whether PostgreSQL was
going to be up to the task. It just so happens that it had a million
records in it as well. The first vacuum took a very very long time,
subsequent vacuums, however, took much less time.
What does vaccum do that takes so long and is there a way to speed this up?
Apparently it does some "database stuff." Yikes, someone else will
have to answer that question. I just know how to get data in and out
of PostgreSQL.
