Hello,

Finally, I made some improvements and run minimal performance 
tests against command-line curl. I wrote simple code for file 
download using dlang-requests, run it and curl for the same 
urls(httpbin server on my notebook) and compare "total", 
"system", and "user" time for different cases. You can find 
numbers and code below.
So my conclusion is - performances are comparable for these 
cases, but there is some field for improvement in dlang-requests.

Case 1 - 50Mb of random data, no any encoding
Case 2 - 50Mb of random data, transfer chunked
Case 3 - 50Mb of random data, transfer chunked, content gzip

           measured times, sec

      |   user    |   system  |   total
