But fixing send() to use a configurable blocksize seems more useful.
Also, users of requests do not have access the underlying connection, so
they cannot use preferred buffer size.
When reading from /dev/zero and uploading to server that drop the received
data, larger buffer size gives 3X more throughput *and* 1/3 of cpu time.
With real storage and network, the effect will probably be much smaller.
The commit message contains much more information than the NEWS and What's New entries. Maybe the What's New entry can be completed, I don't know. In the meanwhile, I close the issue :-) Nir: Feel free to create a new PR if you want to complete the What's New entry ;-)
