As requested offline, an example drawing 150,000 random size circles at random positions in just over 1 second (in simple Perl):

#! perl -slw
use strict;
use GD;
use Time::HiRes qw[ time ];

sub rgb2n{ unpack 'N', pack 'CCCC', 0, @_ }


my $im = GD::Image->new( 1920, 1080, 1 );

my $start =  time;
for( 1 .. 150000 ) {
    $im->filledEllipse( rand( 1920 ), rand( 1080 ), (10+rand(2)) x 2, 
+rgb2n( (255) x 3 ));
}

printf "Took %.9f seconds\n", time() - $start;

open PNG, '>:raw', 'junk.png' or die $!;
printf PNG "%s", $im->png;
close PNG;

system 1, 'junk.png';
