I was just playing a little bit with bcache and it works fine. But if I try random IOPS writes (writeback) on a file larger than the cache, it seems not to work? At least I get a performance as without bcache. Did I miss something? Is caching disabled in such cases? Has anyone a hint for me, what is going wrong?
Bcache has some specific handling of sequential I/O: http://evilpiepirate.org/git/linux-bcache.git/tree/Documentation/bcache.txt Could this explain what you're seeing?
