Description

Hi, we have an customer who have existing lustre filesystem (usage is about 60-70%). When they mount the lustre on the clients and start the IO the client, the initial IO performance is always slow.
When it writes the files and remove them... repeating many times, the system is going to be normal and IO performance is back.
This is odd behavior, but it always happens after the lustre starts.
