Re: [wxperl-users] alternatives to POE

We are sliding way sideways here...

Threads and cooperative multitasking are not mutually exclusive.  To =
really get optimal performance for your cpu cycles & memory buck, using =
both is ideal.  IMHO, this is more true when the CMT technology is also =
an event loop.

However, I totally agree with you in principle Foo.  Using rock spears =
(and struggling to melt copper) in the iron age.  If perl wasn't one =
hell of a good rock spear this wouldn't be so much of a concern.

I must have missed something somewhere...is 5.10 & 6 going to have =
something new on the threading front?

You mean a non-blocking socket call. If I understand POE correctly you
have to alter the flow of the code so that the application operates on
the concept of states. So we're back to cooperative multitasking, which
I find unnecessary given the maturity and stabilty of today's OSes,
including Windows.

I don't think with 5.8.x there's much that can be done. I do look
forward to 5.10/ 6.0 where I expect threading to be on par (at least)
with the current flavours of programming languages. Perl really needs to
have something to show for this year, imho.

Don't see me as a whiner on the downsides of Perl. There are quite a few
workarounds on this issue, so life goes on. Even then, workarounds are
merely short-term measures.
