Hello, I have been doing several benchmarks (Phoronix test suite, disk suite) and I'm really impressed with the performance when doing writeback caching. For the benchmarks I did a git checkout and compiled the 3.1.0+ kernel. As the wiki is outdated I am wondering if the patches have also been applied on a kernel version which is used by server oriented distributions, meaning kernel version 2.6.32 for example or if there is a way to apply the patches (if they exist separately) to kernel version 2.6.32 . I am interested in this specific version of the kernel as other constrains impose it. Also ... do you think that your code is production ready when using bcache to do writeback caching ? Of course I will keep testing but I'd like to know if you think the code by now is production ready. Basically I plan to run a setup like: bcache device assembled from software raid10 or raid0 (4 disk) + ssd ; on top of this a volume group ; on top of logical devices drbd setup . We are running this for a long while without bcache so the setup is stable and the new part here would be bcache. P.S. during the benchmarks bcache outperformed in every way flashcache (I tried two different sequential size settings with flash cache, both underperformed) Regards, Alexandru Ionica -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
