mdadm raid6 sequential read slower than reading from userspace

? How can I find out what bottleneck? I couldn't see anything obvious like 100% cpu usage. I tried copying different tuning instructions I found on Google, but they usually made negative impact if any. I attached the program, but I'm still learning programming so it's not very good. -- Stevie Trujillo
