On one database server, we have both MySQL und PostgreSQL running, and
via script make a fulldump. We see that MySQL is more than twice as fast
for that:
mysql 5.1: 100s (1.66 Min) 1110224519 Bytes, 10.58 MB/s
postgres 8.4: 133s (2.21 Min) 654205642 Bytes, 4.69 MB/s
The commands are:
1) mysqldump --single-transaction --flush-logs --master-data=2 --all-
databases --add-drop-table
2) pg_dumpall -c
What can I do to improve pg_dump performance?
