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

I'm still investigating these results. The reason for this preliminary article is a shout-out so if anyone has any insight to share on the Bcache results, that would be interesting to see in the forums. From these mostly synthetic disk benchmarks at least, the BCache cache didn't actually serve much good on this particular setup. Bad hardware combination? Bad defaults? Do the tests need to wear in for much longer than a few times before the cache becomes useful? Regression in Linux ~4.1? I'm happy to run more tests so stay tuned for updates on this investigation into BCache.
