[HttpComponents] HttpCore vs HttpClient 3.0; performance bechmarks
Based on my (rather limited) tests HttpCore appears approximately 35% to
18% faster than HttpClient 3.0 depending on the document length. Memory
footprint is much more difficult to quantify. Nonetheless, evidently
HttpCore appears to require 2.5 times less GC sweeps for the same unit
of work.
I'd love to hear if others can reproduce similar performance gains for
their respective platforms. Please note, though, test results can be
easily distorted by the HTTP server configuration (logging, connection
keep-alive, etc)
