Fix for: How much speedup does a hyper thread give? (in theory)

Low Risk

As others have said, this depends entirely on the task. To illustrate this, let’s look at an actual benchmark: This was taken from my master thesis (not currently available online). This shows the relative speed-up1 of string matching algorithms (ev…
