Pharo-1.3-13315-OneClick crashing

I posted some info how to crash the newest Pharo with Seaside under
heavy traffic. Just do not know, where to leave that information:

I already saw your blog post about this and thought of leaving a comment.

It is tempting and seems to make sense to do this kind of benchmark or load testing. I have been there myself.

However, benchmarking Seaside is difficult (you are essentially testing session creation speed).
Actual performance depends on many factors such as the adaptor, image, vm and OS being used.

Please search the Seaside and/or Pharo mailing lists for more information.

You have to believe that it is possible to get good real life production performance, it is sometimes just a bit more difficult than starting an image and hitting it hard.

Sven,

ok, actually benchmarking was not my initial idea behind these tests. I
wanted to see, what happens, if VASmalltalk (which was my primary test
candidate) gets under heavy query traffic and to see how load-balancing
works under Apache and VASmalltalk.

And then I looked at the other Smalltalks - and with the newest Pharo
the virtual machines seems to crash.

I've also downloaded a seaside-squeak-3-0-6-all-in-one package and this
worked without problems.

It was also strange to see, that the system does NOT crash, if remove
"-c" command flag in that test (not concurrency requests).

I also tested the Swazoo Adapter - same problem.
