Pynetdicom StoreSCP - Performance

[gswitch]

Hi Scaramallion,
Alright?

I don't know if this is the channel for doubts, forgive me if I'm wrong.

I've been working with Orthanc for about 4 years, but now I met Pynetdicom and I was very happy with its documentation, examples and everything it offers, congratulations on the work!

My goal is to migrate to Python, using pynetdicom and pydicom, so as a challenge I created mystorescp.py with example code and everything worked, but to my surprise, when receiving larger files (Mammogram or RX) it is very slow, and it can be to 1 minute to save the received .dcm file.

So to compare, I used dcmtk's storescp and then I submitted the same study and it gets it instantly.

All tests were done "localhost".

Am I missing something?
Is this performance on pynetdicom normal?
Any help would be most welcome.

This is mystorecp.py:

After researching a lot, I got this PR(#651), comparing with my version (dul.py) they are different, I imagine that this PR should be released in future versions, am I right?

Just for testing purposes, I made the same PR changes and it really solves the performance problem.

Special thanks to Matthew for helping with this issue.

I did the installation like this:
pip install pynetdicom

Why do I get a version without this important improvement?
Are there any other more active channels? How a Forum?

Thank you all!
