I'm certainly not wedded to pgbench, give it a try. BTW, I forgot to mention that it would be useful to try different wal_sync_methods along with this. The reason why it seems unlikely the patch is useful on Linux is that the sync methods that use O_DIRECT probably dominate using the patch anyway. There may or may not be a similar dependence on sync method on other kernels ... regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
