Answer : It can be achieved using dd command.
Example to test write speed :
1. Go to the directory location where you want to perform the test.
| [root@server ~]# cd /dir |
2. Run dd command below.
| [root@server ~]# dd if=/dev/zero of=dd.data bs=4k count=200000 conv=fsync 200000+0 records in 200000+0 records out 819200000 bytes (819 MB) copied, 8.47374 seconds, 96.7 MB/s [root@server ~]# ls -la total 801588 drwxr-xr-x 2 root root 4096 Oct 22 12:51 . drwxr-x--- 5 root root 8192 Oct 22 12:51 .. -rw-r--r-- 1 root root 819200000 Oct 22 12:51 dd.data |
Example to test read speed :
| [root@server ~]# time time dd if=/path/to/bigfile of=/dev/null bs=8k |
if = name of input file
of = name of output file
bs = size of block
count = number of block
conv = fsync - flush data at the end of the copy
dsync - flush data after every block of the copy
