It might be that you misunderstood commit_delay. It will not only delay the disk write, but also block your connnection until the write actually is performed. It will rise the throughput in multi-client scenarios, but will also rise the latency, and it will absolutely bring no speedup in single-client scenarios. It does not decrease safety (in opposite to fsync=off), data will be consistent, and any application that has successfully finished a commit can be shure their data is on the platters.[1] HTH, Markus [1] As long as the platters don't lie, but that's another subject. -- Markus Schaber | Logical Tracking&Tracing International AG Dipl.
