Pax Web 8 performance (different JDKs)
Good evening!
I've just pushed last commit before 8.0.0.GA. This commit fixed the
compilation and test problems under JDK17.
Current state is:
- all the tasks I've planned for 8.0.0.GA are finished
- all the tests (unit, pax-exam-container-native,
pax-exam-container-karaf) work on JDK 8, JDK 11 and JDK 17
I expected that everything would work few percent slower on JDK 11 than on
JDK 8 (I observed this performance downgrade on several occasions). What I
didn't expect is that generally everything works faster on JDK 17 than on
JDK 8!
Here's the table:

I hope to write more about "what is Pax Web 8" soon and that the week of
Sep 13-17 will be the week of the release.
kind regards
Grzegorz Grzybek

The gc is way better on modern jdk, even 11 (post update 6x IIRC for
openjdk but not oracle jdk which was more conservative).
There was also quite a bunch of optim in common operations - like some
String ones.
Can be a way to explain why it is faster.

Hello JBO
Pax Web 8 own "Karaf tests" work (since yesterday) on Karaf 4.3.3.
Everything should work on all Osgi Core R6+ runtimes
(pax-exam-container-native tests use osgi.core 6.0.0 / Felix 5.6.12)

Hi Greg
Thanks for the update and great results !
I’m running a new build/pass and I will test in 4.3.x.
What I have in mind is to prepare 4.4.x with Pax Web 8 and OSGi R8.
So, I would create karaf-4.3.x branch and update main to OSGi R8/Pax Web 8.
Thoughts ?
Regards
JB
