Expression2 is laggy

[Zvbhrf]

Describe the bug

Unfortunately, new compiler is perf-heavy.
I host a build server where people often fight with each other on vehicles like tanks, cars, etc. They use Expression2 mostly for hud stuff or to rotate certain parts of their vehicles. Most of the their code is 20-80 lines of code.

There were ~35 e2's and ~15 players during this profiler session (~8 seconds!)

This did not happen with old compiler at all.

Note

Current compiler.lua version on my server: https://github.com/wiremod/wire/blob/a201ecb60a5109887128b65c9bfbef7f5a5dd8e6/lua/entities/gmod_wire_expression2/base/compiler.lua

How to reproduce the bug

Players place tanks, planes and fight with each other. I suppose random dupes/advdupes from workshop can cause this too, since most of my players use the same e2 code from workshop builds.

Pretty sure e2 has always been laggy even before the compiler update. If you want to test and show that performance was better before, I'm sure there might be a possibility of reverting it.

[Zvbhrf]

Is there any way to revert compiler to the old one just to test?

[thegrb93]

git checkout f65ee9240f23543e9d4666e885c7b1f24ad101d9 will take you back in history before the compiler update was merged.

Keep in mind some e2s will not work in that version.
