Application response time is very slow
Suddenly, without any change in network scope, the application response time is very slow.
1. Connect via SSH to the server.
2. Determine on which partition the data folder is mounted with the command (the output could be for example: /dev/sda):
> df -h /data
3. Check the I/O read speed of this last one with the following command:
> sudo hdparm -tT
4. If the speed of timing buffered disk reads is under 100 MB/sec, check disk health status.
5. If speed is correct, contact us for a deeper investigation.
