Correct me if I'm wrong:
- If you keep using Emacs for hours (that is "typing/moving the point
around") without taking a 30 sec break, then the timer won't trigger
the desktop saving. Right?
- The sluggishness would only be noticed if you happen to do nothing for
more than `desktop-auto-save-timeout' but for less than
desktop-auto-save-timeout + "time needed for saving". It seems
improbable that this happens _often_.
- I've used desktop-mode for years and I've never noticed any
sluggishness as it takes less than a fraction of a second to save.
I've had crappy computers, but admitedly most of them had an SSD. My
current timeout is 5 and I don't see any performance impact even on a
bad computer with an even worse HDD.
Either way, the default value is not that important since every user is free
to change the value. What is more important is to document it
properly. Something in the line of:
> If you experience any irresponsiveness everytime desktop gets saved,
> increase the timeout.
> If not, it's safe to have it around 10.
What do you think?
Cheers!
