Load Comparison - PyCurl vs HTTPClientFactory + Deferred

Test description
Jakarta Jmeter was used.
In 200 threads, 100 requests were sent to the same server, but with random data (to exclude caching). I ran it on an ordinary working machine with a GUI - so for a rough estimate.
Test results

One mistake - the base failed, so the error can be neglected

Distribution Charts
Blocking (PyCurl)

Non-blocking (deferred)

Summary
As can be seen from the result, defered has a minimum server response value of almost 2.5 times less (due to a database failure), and a maximum value is half that of a blocker. The average is also less than 2 times.
Of course, I did not discover America, but at least - now I have specific numbers on hand. I hope they come in handy for someone.
