Why is the time of reading Datastore(use Transaction ReadOnly) getting more and more quickly?

Dear all,

Please ignore my last email, I pressed the wrong button. My question is why reading Datastore(use Transaction ReadOnly) becomes faster and faster? I run my test on physical switch and I record the required time to read port statistics from Datastore, following is my results:

# of read      Average time per read
2000            0.212 milliseconds
3000            0.122 milliseconds

Is it because there exists something like cache in Datastore? Thanks in advance.

Best regards,
