[Bug 1396856] Re: block size limit for partition moving slows down fast devices

[Karl-Philipp Richter]

In the meantime I know that on the system where I suspected the issue to
exist the I/O had a lot of issues unrelated to `garted`. It does no
longer exist, but there seems to be no problem while copying with the
tested block sizes after all. Thanks for your input.

Title:
  block size limit for partition moving slows down fast devices

Status in gparted package in Ubuntu:
  Invalid

Bug description:
  When I move a 200 GB partition on a 500 GB SSD which usually writes up
  to 300 MB/s I only get 50 MB/s write speed and the algorithm to test
  the best block size only 1,2,4,8 and 16 MiB. 32 MiB should be tested
  in order to avoid the block size to become the bottleneck of the move
  operation.
