I'd written a JVM project a while ago that also spent an ungodly amount of time in GC. You can create bottlenecks almost anywhere given enough (lack of) effort. Who knows how finely tuned these projects were or what their load was like before a rewrite. A rewrite in a new language gives you more benefits than just the new language , it also gives you the benefit of hindsight. The ability to fix mistakes made in the first implementation can go a long way.

That's a very good point with these rewrite stories - you could happen to rewrite some really poor code while porting and boom! Language Y is 50% more performant!
