You should be able to vaguely claim that Python and Java are inherently slower than Rust/C/Whatever. I agree claiming that it is 100x slower is a bit unfounded, but it's pretty easy to go find existing benchmarks that show results like this.

Yes, it's exactly as you say.

I did search for benchmark comparisons and bumped into one that had 2 orders of magnitude difference.

But naturally, isolated benchmarks can't encapsulate the whole picture because there's a world of difference between testing how fast a loop runs and performance in production.

I guess that arithmetic operations are not very slow in Python, but if you use objects, then Python performs complicated lookups for every field or method access.

One is not like the other. Java is much much closer to C/Rust than Python is to Java.
