buffer: improve `base64` and `base64url` performance #52428

anonrig · 2024-04-08T18:07:00Z

The work is mostly done by @lemire.

Suggested changes improves the performance of base64 and base64url operations.

Be aware that when doing many comparisons the risk of a false-positive result increases.
In this case, there are 5 comparisons, you can thus expect the following amount of false-positive results:
  0.25 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.05 false positives, when considering a   1% risk acceptance (**, ***),
  0.01 false positives, when considering a 0.1% risk acceptance (***)

Note that gains are not expected for buffers/buffer-base64-encode.js so the 2.95% result is probably approximately 0%. (I am only pointing out that this is not an issue.)

can we have a btoa too, please?

anonrig · 2024-04-08T19:39:52Z

@lemire there are some test cases failing. would you mind looking into them?

@Uzlopak @anonrig

This should be "easy".

lemire · 2024-04-09T01:35:06Z

@anonrig I pushed a commit.

lemire · 2024-04-09T03:34:11Z

@anonrig I did some additional optimizations.

@anonrig If you get around to it, it would be nice to revisit your benchmarks. I bet that you'd get better numbers with the latest changes.

@anonrig If you get around to it, it would be nice to revisit your benchmarks. I bet that you'd get better numbers with the latest changes.

The benchmarks didn't show anything, but I'm pretty sure, it has a flaw.

Hmmm...

For people who want profiling... here are the numbers for the base64 decoding prior to this PR:

Here are the results after...

So the main bottleneck after this PR is merged will be memmove. Unless we find a way to move less data, this function is unlikely to ever get much faster.
