I have installed arch about 4 months back and ever since been experience and Lag/Freezing issue which occurs anywhere from 1-30 seconds at a time. I have been looking for solutions and fixing issues I have found with my system in order to find a solution. It does not seem to be any issue with the hardware, everything is new. I have even gone so far as to swapping out certain parts such as the memory and have even updated the bios firmware.
I believe this is an issue with the way the raid is setup, as harddrive I/O will cease when this happens. If there is something else that may be causeing this issue then I am unsure what it could be.
I have posted my dmesg, mdstat and mdadm.conf files below. Also my system is still experience two bugs. The first one is the RAID initalization failed message durring systm initialization even though the raid array was assembled fine by the kernel. And the other on is the error message from LVM2 durring initalization "File-based locking initialisation failed". That error has supposively been fixed from an update though I am still getting it.

I have been doing some searching around and have found some new information.
https://raid.wiki.kernel.org/index.php/Performance
I found there were some fixes for the "apparent pauses in the stream of IO" that I believed I was experiencing as well. I had in the meantime changed my raid array to raid 5 to increase the read performance which had helped with my lag issue but it was still apparent. So I did two of the optimizations listed on the page. But before I did I ran a benchamark on my current raid 5 array.
Unoptimized Raid 5 array

I think this may have been the root of my problem. When I have used the computer for a few more weeks I will report here again whether or not lag/pause problem has been solved.

SOLUTION!!!
Well I have solved this issue once and for all. It turns out that the hard drives I was using from Western Digital were Caviar Greens which would be fine except. Unfortunately WD and all its wisdom decided to change the sector size from 512-byte to 4KB on there green drives. This I beleive is what was causing the initial pausing issue, I did not bother to attempt setting the sector size of the raid array to 4kb so I am not sure. I removed the drives and swapped them out for Caviar Blacks. I noticed an immediate difference in performance and wouldnt you know it there was no more pausing issue.
It is also possible that the power saving features of the green drives may have been causing the issue as well, I didnt want to waste time finding out.
For anyone interested the drives I was using were the WD20EARS and I swapped them for the WD2001FASS.
