Attempting To Try Out BCache On The Linux 4.1 Kernel
Written by Michael Larabel in Storage on 25 June 2015. Page 2 of 3. 12 Comments

For many of the benchmarks, Bcache writeback (the performant caching mode) didn't actually yield much of an advantage (or any) compared to running the tests against the lone Seagate HDD.

As always, the Phoronix Test Suite runs each test multiple times for accuracy and records the standard deviation. I also carried out the BCache writeback tests a second run after being surprised by the lack of improvement in the results, but that too generally didn't yield much change.
