Hi, i've write some heuristic code for btrfs compression subsystem, userspace option are simple and fast enough (~4GiB/s on my notebook). Heuristic can detect good/bad compressible data, to decrease cpu load and avoid compressing bad compressible data. https://github.com/Nefelim4ag/Entropy_Calculation So, if that looks interesting, please let me know, Thanks. -- Have a nice day, Timofey. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
