Performance benchmarking

DISK IO

Using dd for disk performance tests is not recommended. Because dd will perform a sequential write what is not a real scenario, To evaluate your servers, use fio or bonnie++ for performance tests.

iozone test

iozone -+m <conf_file> -i 0 -w -+n -c -C -e -s 4g -r 1024k -t 8

Actual results:

gluster-block:
        Children see throughput for  8 initial writers  =   87671.01 kB/sec
        Children see throughput for  8 readers          =  133351.47 kB/sec

gluster-fuse:
        Children see throughput for  8 initial writers  =  939760.11 kB/sec
        Children see throughput for  8 readers          =  791956.57 kB/sec

gluster-nfs:
        Children see throughput for  8 initial writers  =  989822.15 kB/sec
        Children see throughput for  8 readers          = 1203338.91 kB/sec
