Antwort: Re: Speed during import - locating the bottleneck

Hi Ronny,

that's a nice improvement. In my Test-Environment (16 MB in small files and
one 80,6 MB file) this brought me a speedup from 9,86 MB/Minute to 15,96
MB/Minute.
Is there another switch like that ...?

ciao

BTW: I'm using an W2K3 Server and a W2K Client

Hi,

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, ...)
Greetings,
Ronny
