Subject: Btrfs send 4-5 times slower than rsync on local
Date: Mon, 27 Jan 2014 11:14:00 +0200 [thread overview]
Message-ID: <52E62358.8030406@gmail.com> (raw)
Hello, i am using btrfs send to copy a snapshot to another btrfs
filesystem on the same machine, and it has a maximum speed of
30-35MByte/sec.
Incredibly rsync is much faster, at 120-140MB/sec. Source btrfs is a
5x2TB raid 0 and target is 1x4TB.
mount options: rw,noatime,compress-force=zlib,space_cache
kernel is linux-3.13.0-rc6-git and btrfs tools is built from git at
about the same time linux-3.13.0-rc6 was released
Finally, is there a way to resume an interrupted send?
