&gt; Yes, calloc() is a few ms slower<p>If you believe a millisecond is a short amount of time you&#x27;re probably not writing video games.  At 60 fps, you only have 16.67 milliseconds to render each frame, so wasting a couple of milliseconds would have a huge impact on what you&#x27;d be able to do for each frame.<p>Luckily, calloc doesn&#x27;t actually take milliseconds unless you&#x27;re making a very large allocation.
