WebSep 22, 2024 · "This is similar to others, but the difference here is that there is no falling through to the next highest number of bytes I can check at once, e.g. if I have 63 bytes (in my SIMD example) I can check the equality of the first 32 bytes, and then the last 32 bytes, which is faster than checking 32 bytes, 16 bytes, 8 bytes, and so on. WebJan 14, 2009 · This lead me to creating a byte [] comparison function after the same code .Net used internally and benchmarking it. For an equal array with 11 elements the unsafe is 3 times as fast. For unequal arrays the managed implementation is quicker if the first or second byte differs. From the third on and out the unsafe gains speed.

You'd get your expected result if you'd use OrderBy ( (Person i) => i.LastName [0]) As for how strings are ordered, it's based on the lexical order of the current locale, not the Unicode code point. There's nothing special about ( or & in Unicode. WebWhat about splitting the byte array into 100 byte segments and comparing 100 segments at a time. Is there a good way to do that?
