That is actually a misconception. You may have this mental classification of Java as a slow language if you looked at its performance 20 years ago. Now it's actually really fast, it goes neck to neck with C++. Sure, Rust or Go or C (or definitely assembler) might be faster in some workloads, but Java is definitely very very fast nowadays. It uses a lot of memory because of the way Garbage Collection works, but it is fast. It's definitely faster than Python, Ruby, PHP and many other kids on the block...
