Your script is reading the whole file, 64 measly bytes at a time, into
a monstrous string $tmp.
Then, finally, when you've loaded the whole [bleep] file into RAM in
$tmp, you just echo it out, right?
Don't do that.
:-)
while (!feof($fp)){
echo fread($fp, 2048);
}
You can play around with 2048 versus 64 versus 1000000 on your box to
see what's "fastest" but I'll be pretty shocked if 64 bytes is the
best performer...
