Matthias,

So long as you specified DB_INIT_LOG and did not set the DB_TXN_NOSYNC or
DB_TXN_WRITE_NOSYNC flags transactions are committed to disk before
txn->commit() returns.  If your measurement was of the average commit
time of many concurrent transactions then you are probably seeing the
effect of our group commit logic which commits several transactions
in 1 write to the log.  Note also that if a transaction does not perform
any updates then txn->commit() will not write any log records.
