All, that I can say, I just lost some time trying to use Hug python server, but unfortunately it can be used only with http 1.0 with debug server. To have 1.1 I needed to use Apache or nginx. I just understood that only in last day, so I decided to write server by myself by standart python library. And as a result I didn have anought time to implement multithreading and to optimise it and it works very slow. Also I didnt have anought time to implement multithreading for threads part. So it can be accelerated ~8 time (top and threads) only by multithreading. And also it could be better to use C-implemented, modern queue based server, it should work much faster with that. :) But, I just worked slowlier then needed and we cant upgrade it without changing the code)
