Ok, as you are testing with JMeter I also tried to replicated the result using
a JMeter script.
Setup:
* Amdatu Platform Release 0.2.1-SNAPSHOT (switching between 2.0.4 & 2.2.0)
* HelloWorld test servlet deployed (project/bin attached).
* JMeter 2.4 running test (JMX attached)
* All running on local quadcore/java6 32bit / win7 64bit.
Results:
* Again I get a small degradation in terms of throughput, similar to my
previous findings (samples attached).
* I cannot replicate the reported degradation.
> Performance decrease servlet requests

> Project: Amdatu
> Issue Type: Bug
> Affects Versions: 0.2.1
> Reporter: Dion Meijer
> Assignee: Bram de Kruijff
> Priority: Critical
> Fix For: 0.2.1

>
> When measuring the performance of a simple servlet with JMeter, there is a
> significant difference between the performance of the 0.1.1 and 0.2.1
> releases.
> This seems to be caused by the update of the org.apache.felix.http.jetty
> library from 2.0.4 to 2.2.0. When using the old library in the 0.2.1
> releases, the performance is good again.
> With 40 concurrent threads, the 2.0.4 version can handle 4640 req/sec, the
> 2.2.0 version 1080 req/sec.
