Have you also optimized your stripe cache for writes?
Not yet. Is it worth it?

Yes, it is-- well, if write speed is important to you that is?
Each of these write tests are averaged over three runs:
128k_stripe: 69.2MB/s
256k_stripe: 105.3MB/s
512k_stripe: 142.0MB/s
1024k_stripe: 144.6MB/s
2048k_stripe: 208.3MB/s
4096k_stripe: 223.6MB/s
8192k_stripe: 226.0MB/s
16384k_stripe: 215.0MB/s
What is your /sys/block/md[0-9]/md/stripe_cache_size?
Justin.
