[Fwd: Re: komodo high cpu usage on <enter>, <tab> and <delete>]

[listmail-3]

I don't know that this will be useful to anyone, but I did come to a
resolution by updating to the latest video driver provided by Dell and
tweaking Norton Corporate edition using the following link:
http://service1.symantec.com/SUPPORT/ent-security.nsf/docid/2005042710304248

While the CPU usage for Komodo hasn't really changed, my screen updates
are real time and therefore editing is back to the way it should be.

No here-docs.    I was able to *somewhat* regenerate the issue by simply
generating a 9k line file.  I don't know that it is quite as slow *but*
the delay in scrolling (using mouse drag on scroll bar) and editing is
still evident on my end.  I don't have any issue editing CGI.pm.  I
suppose it can be affected by total words, as opposed to lines, or even
multiple multi lined statements.

#create test.pl (use chmod u+x)
#! /opt/ActivePerl-5.8/bin/perl
use strict;
use warnings;

print "print(\"This is generated line data\\n\");\n" for (1..9000);

$ ./test.pl > gentest.pl (used unix for speed)

open gentest.pl in Komodo on windows, find some point mid file hit enter
to create a new line, and hit tab a few times.  If no delays are evident
on your end then perhaps have task manager up with komodo.exe
highlighted, during this, and see if CPU rises to 99 and actual
maintains it for about 4-5 seconds.  I imagine you will have more
options enabled than I so if you don't see any issues then I'll agree it
must be something on my end.

Thanks for the update.

We also have this bug, tracking ideas on why editing performance may
have changed somewhat with the Komodo 4.4 release:
