Package: kile
Version: 1:2.1.0~svn1014763beta2-1
Severity: normal

When writing large documents the syntax checking/highlighting uses high rates 
of CPU
(near 100% 1 core) and delays the editing of seconds
(on a 4 cores machine with 8 GB of RAM, for a document of 9000 lines).
This is typical in situations where there is a pair of tags to match like e.g.
1) I have $x$
2) I delete $ => $x and kile starts to rescan the whole file.....
3) I have to wait a couple of seconds to see the other characters I typed, say 
yz$ inserted to give $xyz$.

Naively I would suggest that syntax checking/editing should be immediately 
interrupted by new editing,
or that hightlighting needing a scan of the whole file, like matching pairs of 
$, should wait for a threshold time 
of 2-3 seconds of inactivity before starting.

Hope the situation will improve,
because this reminds me of the old times when people typed in X terminals 
connected to overloaded Sun stations....
Good luck
