Someone wrote a really fun study about the CPU and Time overhead of Garbage Collectors in the JDK.
The paper finds that a GC can cost you somewhere north of 80% of CPU cycles and Time (ie, 80% more CPU cycles or Time used due to GC) at minimum and concludes that a low overhead GC remains "elusive".
And hence I like Rust, where the GC is a lie and my Types are turbofishing into yesterday.
