The speed came from the newer kernel, because CPU usage now is about 25% before about 60%. I think the bottleneck now is the PCI SATA controller. Setting thread count to 2 or higher actually decreases performance.

Woooha with 3.16 backported sync speed pretty much trippled (27 MB/s -> 80 MB/s). Well thanks again!

Oh god I actually misread the 3.2 in the sysinfo for 3.12. time for coffee. Thanks a lot!

Hello all,

I'm running 2.2.5 on a dual core Atom machine and I am just building a RAID 5 array with software raid. Well, the speeds are not amazing. I thought to speed up the array by making the hash calculation multithreaded which should be possible by

echo 2 > /sys/block/md127/md/group_thread_cnt

since Kernel 3.12. But there is no entry group_thread_cnt in the sysfs. Is our kernel build without this or is there a way to enable?

Thanks
