Big-O for Eight Year Olds? [duplicate]
....
There's nothing special about halves, though -- if you can only ignore 10% of your input at each step, it's still logarithmic.
O(n) - you do some fixed amount of work per input element. (But see below.)
O(n log(n)) - there are a few variants.
You can divide the input into two piles (in no mor...
C++ performance challenge: integer to std::string conversion
...t test under VS, but this seems to be faster than your code for g++, about 10%. It could probably be tuned, the
decision values chosen are guesses. int only, sorry.
typedef unsigned buf_t;

unsigned above = val / 10000;

How to create GUID / UUID?
... the increased processing, and it performed the same on desktop, and only ~10% faster on mobile.
The final optimization technique to apply - unroll the loop. Since we're looping a fixed number of times, we can technically write this all out by hand. I tried this once with a single random variable...
Performance optimization strategies of last resort [closed]
.... Ask yourself, does it really matter if the answer is out by 1%? 5%? even 10%?
Down-sides: Well... the answer won't be exact.

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.

What's the difference between utf8_general_ci and utf8_unicode_ci?

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...

You might decide your main band looks okay altered 10% up-or-down, and squash it 900 x 1000 on the 1333 x 1000 screen, leaving 433 x 1000. Then stretch it to 1100 x 1000 on 1666 x 1000 screen, leaving 566 x 1000. So your second band now needs to adjust over only 433 to 566, w...
