You''ll see from the below that while the log device is pegged at 15MB/sec (sd5), my directory list request on devices sd15 and sd16 never are answered. I tried this with both no-cache-flush enabled and off, with negligible difference. Is there anyway to force a better balance of reads/writes during heavy writes? extended device statistics device r/s w/s kr/s kw/s wait actv svc_t %w %b fd0 0....
