Warner Losh 476dfdc3bf Do not relocate extents to make them contiguous if the underlying drive can do ... deletions. Ability to do deletions is a strong indication that this optimization will not help performance. It will only generate extra write traffic. These devices are typically flash based and have a limited number of write cycles. In addition, making the file contiguous in LBA space doesn't improve the access times from flash devices because they have no seek time. Reviewed by: mckusick@		2015-10-16 03:06:02 +00:00
