Ran FIO test and collected performance results on following scenarios

Test1:
  1. Created thin LVM volume
  2. Run FIO 3 times on thin LVM volume
  3. Created thin snapshot and immediatly deleted the thin snapshot
  4. Run again FIO 3 times on thin LVM volume
  Note: Attached results to raw_perf.txt which contains output of `dmsetup status` & `dmsetup table`
