Bug#45476: kate works very slowly when syntax coloring is enabled and the document is big (more than 2000 lines)

Package: kate
Version: 2.0 (using KDE 3.0.0 )
Severity: normal
Installed from:    Red Hat Linux 7.2.93
Compiler:          gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-110)
OS:                Linux (i686) release 2.4.18-3
OS/Compiler notes: 

If you are working with a long document (more than 2000 lines, for example) and the syntax coloring is enabled, kate works very slowly when, for example, trying a word search. Also, as you type a word, you can see that the cpu consumption is very high... Whenever, when the syntax coloring is not enabled, those problem does not arise, and kate works fine.

I have Red Hat 7.3, and KDE 3.0. 

KDE 2.0 works fine with syntax coloring and large documents...

I have not very good english... sorry

Thanks.

Jose
