When i stop my website and i try to run disk speed this is what i have.



# dd if=/dev/zero of=tempfile bs=10M count=1024 conv=fdatasync,notrunc status=progress
10622074880 bytes (11 GB, 9.9 GiB) copied, 46.0385 s, 231 MB/s
1024+0 records in
1024+0 records out
10737418240 bytes (11 GB, 10 GiB) copied, 92.1228 s, 117 MB/s


So, current i can push up to 120 MB/s and iotop report i do 60 MB/s, why i'm high load IO issue if only i'm using half speed?



How i can tweak or fix this problem? i'm using nginx to serve mp4 videos.

      When i stop my website and i try to run disk speed this is what i have.



      # dd if=/dev/zero of=tempfile bs=10M count=1024 conv=fdatasync,notrunc status=progress
      10622074880 bytes (11 GB, 9.9 GiB) copied, 46.0385 s, 231 MB/s
      1024+0 records in
      1024+0 records out
      10737418240 bytes (11 GB, 10 GiB) copied, 92.1228 s, 117 MB/s


      So, current i can push up to 120 MB/s and iotop report i do 60 MB/s, why i'm high load IO issue if only i'm using half speed?



      How i can tweak or fix this problem? i'm using nginx to serve mp4 videos.
