Well, it's not just code size in terms of disk space, it is also code
complexity, and the level of knowledge, skill and time it takes to make use
of something.
And if something fails in an unobvious way in Twisted, I imagine that
requires somebody highly skilled, and that costs quite a bit of

Hi,
The following is a little bit involved, but I hope can make the problem clear.
Using poetry I have written a dummy application which just uses to typer
to illustrate a possible interface design. The directory structure is a
follows:
$ tree -P *.py
.

I’m happy to announce a new release of attrs!
attrs is the direct ancestor of – and the inspiration for – dataclasses in the
standard library and remains the more powerful toolkit for creating regular
classes without getting bogged down with writing repetitive boilerplate code:

You can make backlog very large, if that makes

Well, I was thinking of following the socketserver / handle layout of code
and execution, for now anyway.
It wouldn't be a big deal to make them block, but another option is to
increase the sleep period 100% for every 200 waiting connections while
waiting in handle.
Another thing is that it's

Hi Martin.
I was thinking of doing something with the handle function, but just this
little tweak:
https://github.com/morphex/stp/commit/9910ca8c80e9d150222b680a4967e53f0457b465
made a huge difference in CPU usage. Hundreds of waiting sockets are now
using 20-30% of CPU instead of 10x that.
Hi Barry.
Well, I can agree that using backlog is an option for handling bursts. But
what if that backlog number is exceeded? How easy is it to deal with such
a situation?
I just cloned twisted, and compared the size:
morphex@morphex-Latitude-E4310:~$ du -s stp; du -s tmp/twisted/
464 stp
OK, I'll have a look at using something else than _threading.
I quickly saw a couple of points where code could be optimized for speed,
the loop that transfers data back and forth also has low throughput, but
first priority was getting it working and seeing that it is fairly stable.
