Tux Paint now starts up in just over 1 second, 640x480, with everything enabled. Memory usage has dropped dramatically. Stamp scrolling will be a bit rough the first time through; that is fixable with a prefetch process in case it matters. There are two empty functions, flip_surface() and mirror_surface(), that need code.
Very little is now kept in memory. Each stamp get a 5-word struct. Once scrolled to, sound and text may get attached to this struct. It would be good to free the sound data when not needed, but I'd have to see what SDL thinks of that. (the sound might be playing) Here is some data from the "top" program: PID USER VIRT RES SHR S %CPU %MEM TIME+ COMMAND 8696 root 157m 137m 25m S 0.0 27.3 315:57.14 XFree86 8812 albert 128m 93m 45m S 0.0 18.6 60:29.86 firefox-bin 8838 albert 128m 93m 45m S 0.0 18.6 0:00.15 firefox-bin 8839 albert 128m 93m 45m S 0.0 18.6 0:04.73 firefox-bin 8841 albert 128m 93m 45m S 0.0 18.6 0:37.76 firefox-bin 7382 albert 128m 93m 45m S 0.0 18.6 0:00.02 firefox-bin 9536 albert 85500 73m 9264 S 0.0 14.7 0:17.64 tuxpaint.old 9537 albert 85500 73m 9264 S 0.0 14.7 0:00.00 tuxpaint.old 9538 albert 85500 73m 9264 S 0.0 14.7 0:00.00 tuxpaint.old 9539 albert 85500 73m 9264 S 0.0 14.7 0:00.00 tuxpaint.old 9540 albert 32292 21m 9268 S 0.0 4.4 0:00.69 tuxpaint 9542 albert 32292 21m 9268 S 0.0 4.4 0:00.00 tuxpaint 9543 albert 32292 21m 9268 S 0.0 4.4 0:00.00 tuxpaint 9544 albert 32292 21m 9268 S 0.0 4.4 0:00.03 tuxpaint So, what is the remaining 21 MB going to? Merging the *.dat file into the *.txt file (or PNG text) would speed things up. Disk seeks are deadly. _______________________________________________ Tuxpaint-dev mailing list Tuxpaint-dev@tux4kids.net http://tux4kids.net/mailman/listinfo/tuxpaint-dev
