  • Simple NFs without Dedup , no client side cache , no compression. On simple system.
dd if=/dev/zero of=test1.img bs=1024 count=10000000
10kb 437kB/s
100kb 4,4 Mb/s
1MB 32.2MB/s
10MB 162MB/s
100MB 204MB/s
1GB 6 MB/s
  • NFS with DEDUP , Client side cache , Inline compression.
10kb 650kB/s
100kb 5,4 Mb/s
1MB 38.2MB/s
10MB 192MB/s
100MB 311MB/s
1GB 339 MB/s
10GB 317MB/s
  • We can see the effect of Dedup when /dev/zero is replaced with /dev/urandom . It performs like normal nfs.
 dd if=/dev/urandom of=test8.img bs=1024 count=1000000
10kb 449kB/s
100kb 3 MB/s
1MB 6.2 MB/s
10MB 8MB/s
100MB 9.9MB/s
1GB 9.8 MB/s
10GB 7 MB/s
