When you say both are extremely slow, do you mean imgstatarray() and
filesize() together?  Because filesize() for me is extremely fast:

<?php

require_once 'Benchmark/Timer.php';
$t = new Benchmark_Timer();
$t->start();

print filesize('./test.bin'); // ~100MB file
print "\n";

$t->stop();
$t->display();
?>

Output:

100000000

I haven't tested imgstatarray().  Maybe that's where your problem is?
If not, maybe it's a problem w/ your OS ... ?
