Hey folks! I'm running some simple benchmarks for my FOSDEM handles talk and wanted to reopen discussion about the performance of non-static-final method handles.
In my test, I just try to call a method that adds given argument to a static long. The numbers for reflection and static final handle are what I'd expect, with the latter basically being equivalent to a direct call: Direct: 0.05ns/call Reflected: 3ns/call static final Handle: 0.05ns/call If the handle is coming from an instance field or local variable, however, performance is only slightly faster than reflection. I assume the only real improvement in this case is that it doesn't box the long value I pass in. local var Handle: 2.7ns/call What can we do to improve the performance of non-static method handle invocation? - Charlie
