How many tk objects are you keeping in memory?
Are you using some kind of a virtual tree control, one that doesn't keep all objects in memory?
On my machine, Scrolled doesn't like more than ~1300 buttons, I don't care why
#!/usr/bin/perl --
use strict;
use warnings;
use Tk;
Main( @ARGV );
exit( 0 );
sub Main {
gogogo( shift || 6_200 );
}
sub gogogo {
my( $max ) = @_;
my $mw = tkinit;
for my $ix ( 1 .. 3 ){
my $button = $mw->Button( -text => "Make $max" )->pack;
my $frame = $mw->Scrolled('Frame')->pack(qw/ -expand 1 -fill
+both /);
$button->configure( -command => [ \&makesome, $frame , $max ]
+);
}
$mw->MainLoop;
}
sub makesome {
my( $frame , $max ) = @_;
$frame->Busy;
my $button = $Tk::event->W ;
$button->configure( qw/ -state disabled /);
$button->update;
$frame->update;
my $time = time;
print "$frame ( $max ) $time\n";
for my $ix( 0 .. $max ){
my $button = $frame->Button( -text => $ix )->pack;
$button->configure( qw/ -state disabled /);
}
$frame->update;
$frame->Unbusy;
my $time2 = time;
print "$frame ( $max ) $time2 #### $time2 - $time = @{[ $time2 - $
+time ]}\n";
return;
}
But FWIW, Firefox doesn't like a lot of buttons either, and frankly, that many actual button objects is too many -- same as displaying 1000 search results, for human not to go insane, you have to pageinate

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
