Optimizing the overhead of the sleep command

[ko1nksm]

As with any other command, there is an overhead in executing the sleep command.

# FALL_SPEED_LEVEL_15=0.007
$ time sh -c 'i=0; while [ $i -lt 1000 ]; do i=$((i+1)); sleep 0.007 > /dev/null; done'

real	0m11.345s
user	0m0.911s
sys	0m1.748s

I would like to eliminate this. I suspect that measuring the execution time of the sleep command will improve this issue. I don't know if this will work, but I am going to give it a try.

I impressed for your help. Very thanks!

I will implement the line clear effect and lockdown effect.

I'm not sure how useful this feature will be, so I plan to implement an option to change the sleep method.

OK!

I'm thinking of doing this in my own repository, so I'd like to close it from here. When it is done, I will create a PR as before. It may take some time.
