Yes.

Yes on my laptop (Debian 6 / 64 bits / openjdk 1.6u18)
in attachment JMeter testcase.
With HC4 impl:
summary = 2590 in 72.4s = 35.8/s Avg: 994 Min: 487 Max: 4806
Err: 0 (0.00%)
Stats at ~ 72secs :
netstat -tuplna|grep java |wc -l;
1494
netstat -tuplna|grep java|grep ESTA|wc -l;
167
netstat -tplnau|grep java|grep CLOSE_WAIT|wc -l;
1337
With HC3 impl:
summary = 4498 in 83.2s = 54.1/s Avg: 448 Min: 246 Max: 2489
Err: 0 (0.00%)
Stats at ~83 secs:
netstat -tuplna|grep java |wc -l;
61
netstat -tuplna|grep java|grep ESTA|wc -l;
60
netstat -tplnau|grep java|grep CLOSE_WAIT|wc -l;
0
NB: more requests in same time with HC3.
NB2: HC3 ESTABLISHED connections is lesser than HC4 (60 users in JMeter
scripts)
