May I know the static rule, or the Mathematical basis of the resize_pool?? Really appreciate!

I don't know the reason

Hi, @BrainGithub

There is no esoteric mathematical principle. Just periodically count the ratio between unused list and usage list (count 3 times by default) If exceed the threshold it means that there is too much idle connections then release of some.

I will add more comments and tidy up the code to make the code more readable.😃
