Re: Re: Use thread with good care, but definitely keep using it

Yes, the results would be different on different platforms, especialy for something like thread. As you pointed out, the thread implementations are so different on different platforms.

Even on similar platforms, with a different configuration, the results are so different. I tried:

windows 2k, with a high configuration (not sure about the exact numbers, I am at home now, and that one is at my company). After created 230 threads, the first script exited without error or warning, but quited.
with this win98 at home, low configuration - 32m memory, it quited after 30 threads being created.

On windows, I would expect the setting of virtual memory might alter the results.

I think lots of people probably want to see results on other platforms, as future reference. I have access to unix, but it only has 5.6.1 installed, so useless in this case.

WinXP corp (pro), 640MB RAM, AS 5.8.0 (build 804) dies after approx 333 threads, trying to write to memory at virtual address 4 -- clearly a bug. At that point, I'm 540 MB into swap, going down to 405MB after hitting "OK" to the debug or die dialog box (a dfferance of 135MB, but that doesn't neccessarly mean all that much), and the threads took an average of 1/30s to create (I modified your code slightly). BTW, anybody know if I should perlbug for this, or is this likely to be unrecognizably changed in bleadperl anyway? Warning: Unless otherwise stated, code is untested.
