I am exclusively using Papyrus running on OpenJ9 (https://www.eclipse.org/openj9/)
both on Windows 10 and Ubuntu 18.04
with
-vmargs
-Xshareclasses:silent,fatal
for 6 months by now. The performance enhancement over the Oracle Hotspot engine is incredible. Also the memory foot is significantly lower.

No single issue so far. It runs rock stable.

Who else runs Papyrus on OpenJ9?

I would be interested to know.

I use
openjdk version "12.0.2" 2019-07-16
OpenJDK Runtime Environment AdoptOpenJDK (build 12.0.2+10)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 12.0.2+10, mixed mode, sharing)

Till now had never problems with it. can't compare because i never had another version on this PC.

Hi Carsten,

It seems very interesting indeed. I did not have the chance to try it yet but I'll see if I can switch to it in the next months or so in order to experience the difference propelry.

Cheers,
Quentin

Hi

Some of the direct and indirect discussion on https://bugs.eclipse.org/bugs/show_bug.cgi?id=565563 might be relevant.

There appear to be a distressing number of confounding factors that can make make one Java seem better than another.

Regards

Ed Willink

Thanks Ed,
many, many thanks for your pointer. Interesting, really interesting.
Yes it is tricky, damn tricky, I know. Not only ramp-up behavior vs asymptotic performance is an issue, as your case shows.
That is why I tested with several Papyrus and Capella versions on different OS with different malware protection software on different hardware.
