When iterating diagonals of a 3D array, the performance differences between LabVIEW and Rust become very noticeable. Even with a straightforward implementation, the generated machine code tells a story about what’s happening under the hood.
For some reason, I need a fast method for string search. The LabVIEW Search/Split String function is relatively slow, I’ve done this using String Zilla, and achieved around a 20x boost with AVX2/AVX512.
I just encountered slow string performance in LabVIEW when a large string is passed to a DLL as a C string pointer. It is always better to pass it as ‘Adapt to Type’ instead of a pointer.
In some cases we need to measure a very short intervals (hundreds of the CPU Tacts) directly in Assembler. We can perform measurement by using cpuid/rdtsc combination.
