Performace on NFS
Note: Cleint side cahe is not yet deployed.
- 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 |
