Question about periodic performance fluctuation (for every 45s) during disk performance test
I usually evaluate the disk performance using vdbench.
(It's very good for showing the performance result in detail. thanks)
I have some issues about periodic performance fluctuation for every 45s
I set up the reporting interval = 1s, and every 45s, the performance is fluctuated.
First, I changed the disk to other brand, but same phenomenon occured.
Second, I assumed that this issue is made by garbage collection in java.
Thus, using jstat tools for monitoring java GC, there is no relationship between java gc & 45s performance fluctuation.
I also changed the openjdk-7 to oracle-jdk-8, but the phenomenon still remains.
Is there any background work in vdbench for every 45 seconds?
I hope your kind response
