Just a quick post on an interesting image I stumbled upon today. It really brings into perspective what the slowest part of a computer system is and where your optimizations should be focused on if you want efficiency. Since it’s a large, but thin image, I couldn’t thumbnail it, so you will find it in the link below.
Image: Latency
I would highly recommend you check out the blog post referenced in the image: What Your Computer Does While You Wait
I really like this quote from the article:
Most simple instructions on the Core 2 take one clock cycle to execute, hence a third of a nanosecond at 3.0Ghz. For reference, light only travels ~4 inches (10 cm) in the time taken by a clock cycle.
