Jesper, If they both took the same amount of time, then you are almost certainly bottlenecked on gzip. Try a faster CPU or use "gzip -fast". - Luke ________________________________ From: pgsql-performance-owner@xxxxxxxxxxxxxx on behalf of Jesper Krogh Sent: Mon 4/10/2006 12:55 AM To: pgsql-performance@xxxxxxxxxxxxxx Subject: [PERFORM] Restore performance? Hi I'm currently upgrading a Posgresql 7.3.2 database to a 8.1.<something-good> I'd run pg_dump | gzip > sqldump.gz on the old system. That took about 30 hours and gave me an 90GB zipped file. Running cat sqldump.gz | gunzip | psql into the 8.1 database seems to take about the same time. Are there any tricks I can use to speed this dump+restore process up? The database contains quite alot of BLOB, thus the size.
