Is your feature request related to a problem? Please describe.

OTTL currently has some basic performance benchmarks, but they are not comprehensive or detailed enough to show the full performance picture.

Describe the solution you'd like

We would like to have a comprehensive and rigorous set of performance benchmarks. The goal is to provide clear, measurable data that validates our decision to build OTTL as a native OTLP solution and highlight areas where performance can be improved.

Describe alternatives you've considered

@sfc-gh-sili It would be great to have a better picture of OTTL's performance. Is this something you're willing to take on?

[sfc-gh-sili]

@evan-bradley. Yes, I have some open cycles this quarter, so I'd be happy to take this.
I am thinking of starting off with some common use cases (like what you and Tyler covered last week https://www.youtube.com/watch?v=UGTU0-KT_60) and see how filter processor / transform processor handles huge traffic. Let me know if you have any ideas / advices.

A benchmark for how the transformprocessor handles under load while handling many statements (like 100+ transformations) would also be great. I have seen some very large transformprocessor configs.
