Regex performance differences AMD64 vs ARM64 about node

[rluvaton]

The regex is part of the ECMAScript, thus the performance is caused by v8 rather than node

You can test that when using d8 to check if that happens in v8 as well

It does happen on d8. On a Macbook with M2 chip (Arm64), I am able to compile for x64 and for Arm64.
The same performance difference for the gist code is verified - arm64 much slower than x64.

When profiling:

• ARM64: Statistical profiling result from v8.log, (1384 ticks, 1383 unaccounted, 0 excluded)
• x64: Statistical profiling result from v8.log, (66 ticks, 26 unaccounted, 0 excluded).

If so, than there is nothing much for us to do, you can open an issue in v8 issue tracking page
