My DCTC2016 talk: Linux MD RAID performance improvement since 3.11 to 4.6

Filed under: Great Days,kernel — colyli @ 3:11 am

This week I was invited by Memblaze to give a talk on Data Center Technology Conference 2016 about Linux MD RAID performance on NVMe SSD. In the past 3 years, Linux community make a lot of effort to improve MD RAID performance on high speed media, especially on RAID456. I happen to maintain block layer for SUSE Linux, back port quite a lot patches back to Linux 3.12.

From this talk, I list a selected recognized effort from Linux kernel community on MD RAID5 performance improvement, and how much performance data is increased by each patch (set), it looks quite impressive. Many people contribute their talent on this job, I am glad to say “Thank you all ” !
