Improve Base64 encode/decode performance
For large packet sizes (>1Mb), the Base64 encode/decode functions are not performant.
Investigate and see if improvements can be made to increase library performance.
I'd love some feedback on this library, performance-wise. https://github.com/LabVIEW-Open-Source/Serializer.Base64
I know it is 15% faster than the one found on NI forums for short strings (such as PEM certificates), but I have not tested it for large payloads. I assume a sort of in-place algorithm is what you're looking for... I'm interested in working on this. Let me know.
ok, this one is really a gem: https://forums.ni.com/t5/Example-Code/Fast-Base64-Encoder-Decoder-using-LabVIEW It is MIT license, so I'll include in the one I mentioned above.
By the way, this is the kind of improvement you're looking at for a 800kB payload:
(I toggled between my take on Base64 and this VI)
It does not check for validity of the string though, such as removing all whitespaces (space, tabs, CR, LF, etc.)
