For future reference and documentation, here the results of the new ZnMessageBenchmark from the current version in 3.0 to Zn+Zdc trunk. The benchmark measures how fast HTTP messages (requests and responses) can be written to or read from an in memory byte stream.

#binaryResponse8k->'Writing 58,100 per second. - Reading 16,300 per second.'
#postRequest->'Writing 20,000 per second. - Reading 9,230 per second.'
#simpleRequest->'Writing 77,100 per second. - Reading 30,600 per second.'
#simpleResponse->'Writing 34,200 per second. - Reading 11,100 per second.'
#standardRequest->'Writing 24,000 per second. - Reading 13,000 per second.'
#textResponse256k->'Writing 163 per second. - Reading 131 per second.'

#textResponse8k->'Writing 4,900 per second. - Reading 4,000 per second.'

Hardware is MacBook Air, 2 Ghz Core i7.

The main difference is due to improvements in character encoding/decoding (fast path implementations). At the same time, the code now implements more features.
