Does putting the XFS log on an SSD significantly improve performance?
- by Paul Wagland
I have a five disk array running XFS in RAID5, and I would like to improve it's performance. I have seen some hints that putting the log onto a separate device can help, does putting the log onto an SSD help dramtically?
In theory, it should, but I have not been able to find any case studies where someone has actually done this, and buying an SSD and then having it not work well would be inconvenient at best…
