[squeak-dev] Re: Re: [Swazoo-devel] Faster connection makes system unrespons ive

Chun, Sungjin
OK, I'll respond on this email.

On Windows, when I run Squeak VM with -headless option, even if multiple(4) file
upload session is running, the system is very responsive. But if I run image with regular
fashion(without -headless option), which means Squeak with its own window(sorry for
my poor description), even single file upload from fast connection can make my
sysetm(laptop) unresponsive.

I suspect Windows scheduling algorithm or something like that does schedule applications
differently from windowless application to application with window. But I'm not sure on this :-)

So, for me, Squeak + Swazoo is good, acceptable platform for file upload/download service.

Thank you.

  I'm sending to the squeak mailing list too, because this Swazoo on
Squeak problem is interesting more broadly.

Thank goes to you first and foremost and reporting all experiences you
had is very worthwhile. Your experience shows possible problems with
Swazoo on Squeak on Vista (or Windows in general) when image runs
headfull, is that true?

So, what's now a difference if you run headless or headfull, when Squeak
GUI doesn't work at all anyway?
