: When I run the app from an uncompressed file system on a test HDD
: instead of flash, the app runs fine. When I try to use ramdisk or tmpfs
: for storing a part of fs (/usr/local directory), the mouse response
: becomes very bad. Mouse seems to move very slowly and the cursor blinks
: rapidly. The refresh on screen seems to have been badly affected.
: Another observation is the characters typed on keyboard take time to
: appear on the screen.
It almost seems like the system may be polling, rather than waiting
for an event. Are you running the same kernel? Perhaps the system
you've built for ramdisk is failing during the select() call, and polling
as a result. I suggest putting a printf() in the mouse driver read routine,
to check whether the application is really waiting for an event, or polling
constantly. The cursor blink is because Microwindows uses a soft
cursor and must hide the cursor on every mouse move, which can
cause a blink if it happens too rapidly. Hope this helps!
