Impact of using thinpool on LVM performance
Using LVM, what are the performance implications of using thinpool on an logical volume?
It depends of type of drive below it. When that's a ssd drive (where random access is simmilar to linear access) - there will be no difference. When using snapshot - there can be some performance boost. But - if there is a magnetic drive(where random access is much slower than linear access) - there will be some performance loss because of jumps to different areas of disk.
In normal operation, none. When snapshots are brought into the mix, thin provisioned LVs perform a lot better.
