Ternary operator is twice as slow as an if-else block?
... x64 CLR, but I can on x86. On x64 I can see a small difference (less than 10%) between the conditional operator and the if/else, but it's much smaller than you're seeing.
I've made the following potential changes:
Run in a console app
Build with /o+ /debug-, and run outside the debugger
Run both...
What's the difference between utf8_general_ci and utf8_unicode_ci?
... sharing. I'm getting sensibly similar figures (MySQL v5.6.12 on Windows): 10%, 4%, 8%. I concur: the performance gain of utf8_general_ci is just too minimal to be worth using.

What are the effects of exceptions on performance in Java?
...situation where the failure is not exceptional. Cutting that down to only 10% massively cuts the performance hit. The problem with this kind of test is that it encourages people to stop using exceptions altogether. Using exceptions, for exceptional case handling, performs vastly better than what y...

Algorithm to compare two images
...ch, you now have a reasonably reliable benchmark. An algorithm that finds 10% positives is not as good as one that finds 4% of positives in our test data. However, one algorithm may find all the matches, but also have a large 20% false positive rate, so there are several ways to rate your algorith...
