I have done some automated scripted tests with bonnie++ over RAID10 and encryption, using different encryption cipher modes to evaluate the impact on I/O operations. The strange thing is that I can see a significant increase in read performance (about 20%) when running the tests DURING the raid resync phase directly after the raid creation as appose to running it after the resync, or after I create the array with --assume-clean (which skips initial resync). Have anyone noticed the same behaviour, and how can it be explained? Any ideas? Can someone else verify that they get the same result? -- View this message in context: http://www.nabble.com/Faster-read-performance-DURING-%28-%29-resync-on-raid10-tp19666016p19666016.html Sent from the linux-raid mailing list archive at Nabble.com. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
