Could you please run them against your test URI?
Tests are done, though they were confusing at the first sight. Warmup
and target URIs always point to localhost. I have swapped them for
config.getUri.

Please note that the remote server does not accept any post requests
without several other preparing requests and additionally require a
one-time ticket. Results may be biased.
This is what I would expect: with a concurrency level below, say, 2000
blocking HC should be somewhat faster than async HC.
The document length looks kind of small to me (1279 bytes). Were you not
talking about downloading some huge file and not being able to saturate
network bandwidth?
Your remarks are correct but reread what I have written above:

To perform real-world test, I have to rewrite the BenchRunner to perform
GET requests only with custom headers filled with one-time-tokens. POST
is used to upload files to the server. This is an area I have not
analyzed yet. Download is happens more frequently that upload.
This is something I cannot do before next week or June.
The issue is somehwere burried between BIO and NIO.
Thanks for the support!
