Search String Performance

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.

Slow String Performance

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.

Large File Experiment

In this “weekend” experiment I’ll write large file (16 GB in my case), then read it back with different buffer size and threads and check the performance.
