Re: Speed during import - locating the bottleneck

Try setting

set_flags DB_TXN_NOSYNC

in $REPOS/db/DB_CONFIG

# Disable fsync of log files on transaction commit. Read the
# documentation about DB_TXN_NOSYNC at:
# http://www.sleepycat.com/docs/api_c/env_set_flags.html

I don't know if the sync is per file, but working with ~250MB Sources and
20.000 files imports, this greatly improved performance.

Beware that this may harm data integrity when using non-server hardware
(secured thru UPS, ...)
