Description Nathan Kinder 2013-12-17 22:28:05 UTC
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/568

Investigations show that setting nsslapd-db-transaction-batch-val does improve performance of concurrent modify operations, but its use violates the durability of the transaction, since the flush of the txn log is delayed a few operations or to when the log_flush_thread runs.
To make use of this feature the synchronization between the worker threads and the flush thread needs to be improved.
