I have an NSTextView which at some point displays a lot of characters (a few hundred million). So far, so fine. Scrolling works nicely, only ca. 30% cpu load and then going back to 0% after the scrolling is finished.
But... at some point -without anything else happening at that moment, no user input, nothing- CPU load jumps from 0% to 100% and stays like this for minutes.
Instruments reveals it is NSTextCheckingOperation -> NSSpellCheckerCheckString -> checkDataDetectors.
I already disabled spellchecking in the xib file as well as programtically.
Any ideas how to prevent this nonsense? ;-)
Thanks in advance!
