Sometimes clients complain about the performance for the GMS server in Virtual Appliance even though they have enough CPUs and RAM in their system. One way to verify this is check the disk performance in their environment.
1. Connect to the GMS using 'Putty'
2. Use the following command to verify disk performance:
[root@snwl GMSVP]# dd if=/dev/zero of=/opt/GMSVP/Temp/100M.tst bs=100M count=1
1+0 records in
1+0 records out
104857600 bytes (100.0MB) copied, 0.565954 seconds, 176.7MB/s
From the above, we can see to write 100MB data to the Temp folder (opt/GMSVP/Temp) it took 0.565954 seconds with a throughput of 176.MB/s
There are no set limit to verify which system is the fastest or slowest. Each depends on client needs. But somewhere below 100MB/s can be consider as low performance disk. We can recommend client to consider replacing the disk at their earliest convenient time.
