I have no good documentation only experience. I have been using
software raid in linux for over 5 years and I have over 15TB of raid
online at the moment now mostly in <$2000 desktop class machines since
they are fast enough to saturate our gigabit network.

Try playing around with this command (assuming your array is md1):

echo 1024 > /sys/block/md1/md/stripe_cache_size

You can try 256, 512, 1024 ...
The effects of this do not stay after a reboot so if you want to keep
this put it a startup file.
