Neil hello. I have been looking at the raid5 code trying to understand why writes performance is so poor. If I am not mistaken here, It seems that you issue a write in size of one page an no more no matter what buffer size I am using . 1. Is this page is directed only to parity disk ? 2. How can i increase the write throughout ?
