Hi,
For your situation (slow machine), you can do two things. Set the
semantic-idle-scheduler-max-buffer-size to something small, like 1024.
Small buffers will parse quickly. Large buffers are slower
(naturally) and would then not be reparsed in idle time.
An alternate solution is what you suggested earlier, set the idle
time to something large. If the idle time is 10 minutes or so, then
chances are you would be off getting lunch, and it would be ok for
Emacs to refresh your edits. Even a delay of 1 minute might push
things off to a point where you would not notice.
The idle timer could also be completely disabled.
It depends a bit on what aspects of semantic you want to use.
Several of the JDE functions, and all senator functions and other
semantic minor modes will request the list of tags from your buffer.
The idle scheduler is there so there is no delay when you call those
functions. If that delay (at command execution time) is preferable to
a delay during editing, then the longer timeout is the way to go.
If you were writing a program that fiddled with parsing in some way
(like the language debuggers in Semantic) then an alternate method
for disabling the idle parser is used to prevent recursive parsing.
