I have a question about target-block-time.

Question

Below is some of the parameters.

target-block-time = 180

pow-minimum-bits = 22

target-adjust-freq = 86400

 

I am mining with one node and Below is the average time per 480 blocks.

No. Block	Average time
1~480	0min 45sec
481~960	2min 24sec
961~1440	3min 4sec
1441~1920	3min 3sec
1921~2400	2min 55sec
2401~2880	0min 48sec
2881~3360	2min 48sec
3361~3840	0min 52sec

As you can see, the average time to 2400 is normal, 

but the average time between 2401 ~ 2880 and 3361 ~ 3840 is too fast.

I did not add nodes and did not other tasks.

Why does this happen?

Answer 1

This could happen if some of your nodes are running on hardware whose performance can change over time, e.g. because they're on a cloud instance which is sharing CPU with other instances, or there are other processes competing for CPU within the same operating system environment. How many nodes are you running?

Thanks for the quick answer.

The total number of nodes is one, and one is mine.

OK, and can you tell us something about the host environment on which it is running?
