Fl::add_timeout dramatically slows system responsiveness in static
linked embedded nano-x apps
From: Luca Santini ####@####.#### Date: 6 Nov 2009 08:54:11 -0000 Message-Id: <4AF3E306.2070408@spesonline.com> Hi all, i noticed this phenomenon and i hope this can help someone. I work on embedded systems (ARM and SH archs) with single non-window-managed FLTK applications. I noticed that system speed grows up if i compile nano-X as a library (no more need to launch the server) but if in my apps there are some Fl::add_timeout/Fl::repeat_timeout/Fl::remove_timeout the performance degrades and system is quite unusable. Solution is: using threads. Fl::add_timeout -> pthread_create Fl::repeat_timeout -> while(1) with usleep() in the thread Fl::remove_timeout -> pthread_cancel regards, L. -- *Luca Santini* //Elettronica di Sistema// *SPES.
