I’m afraid that the patch won’t be officially integrated as long as there is noone who can prove, that the throughput and responsiveness is not harmed.
That’s why I thought your setting and the measures are perfect as they are.

Anyway … a little bit of hope remains that somewhen in the unknown future there will be new tests

thanks for your commment. Heap consumption (and heap turnaround) was indeed a problem for this use case. So this patch might help a lot in that regard. Unfortunately I won’t have the time to perform more tests in the near future, so I can’t promise if and when we can perform any benchmarking. Maybe the benchmarks would also have to be performed slightly different, since my main concern was overall throughput and responsiveness.

For now the wizard seems to run “good enough” on stock RAP. We’ll keep that patch in mind though and maybe we can integrate it in the future either directly or via upstream updates in RAP. So thanks again for your post.

it seems, that you have put up quite a good infrastructure for load-testing and measuring results.
Thanks for sharing the results.

There is one open enhancement request regarding memory consumption (https://bugs.eclipse.org/bugs/show_bug.cgi?id=240143).

The patches there have not yet been applied, because the RAP team is not sure, whether these could have negative impact on performance.

Is there any chance, that these patches could be applied for a short while, just to have some arguments pro/against this patch ?

With the analysis done so far by you, this is a great base for comparisons!

It may be that the problem is a network congestion issue, and I just haven’t had the time to check into it further.

I have experienced some problems as well, and we’ll look into these issues. Do you know if it was a specific combination of components you were selecting? The logs created by the p2 installer might also be helpful for identify the problem.

My primary concern right now is with the wizard, but once that is done, we will need to adress the issues concerning the p2 installation process, like scalability, availability of mirros, etc.
Sometimes the download is just painfully slow and takes almost literally ages. This will need to improve to make this wizard based installation a viable alternative to the traditional downloads.

That being said, I’m still eager to follow what’s going on

To get the demonstration running take a look at
http://wiki.eclipse.org/EPP/Wizard/Demonstration_HowTo which has basic documentation on how to get started, as well as a team project set with all the necessary components.

As this is still work in progress sources, wiki and the running demonstration may not be quite in sync.

Hopefully I’ll be able to update everything by the end of the week.
