Some time ago, accidentally I landed on some web page with a list of common computer system operations with associated time characteristics, sth like:
- CPU cache read – x ms
- Read from RAM – y ms
- Save to disk – …
- Static dispatch – …
- Dynamic dispatch – …
And so on.
It was a pretty long list of (maybe around 30) different operations from very short CPU-related operations to very long I/O operations. It was an old source, so the exact numbers do not hold true any more, but I believe that the ratio of these numbers still holds true and is a good basic knowledge. I’m looking for that web page or any other source with such informtion.
Do you know any reliable source with such info?
