First unofficial BTRFS performance tests.


Florian D. ran a small FIO tests with following configs:

  • sequential read
  • random writes
  • sequential read again
Here are results with filesize:300MB, bs:4K:
   btrfs                  reiserfs               ext3
   usr% sys% bw   sec.    usr% sys% bw   sec.    usr% sys% bw   sec.
1  5    51   68.3 4.6     1    17   67.4 4.6     5    24   68.0 4.6
2  0    1    0.7  431     2    21   29.8 10.5    3    18   29.0 10.8
3  0    1    2.3  133     1    19   70.5 4.4     5    24   68.6 4.5
BtrFS performance is quite bad in that setup.
