I rarely see performance problems that are show stoppers, especially in the cloud, where you can always just buy a bigger node. Usually if something is going to be rewritten C++/Rust/$performant_lang it's that high velocity iteration on the codebase has mostly stopped and we could save 50-60% in infrastructure costs by running it on nodes with less resources. Then naturally you start to factor in the engineering manhours for the rewrite vs the potential savings.
