anyone got any fresh kotlin vs java runtime benchmark?

[gildor]

Benchmark of what?
Most of bytecode is the same or very similar, it highly depends on which feature do you use and style that you prefer

[vpriscan]

I am interested in the object generation while iterating with for loop, specifically when using Ranges

[karelpeeters]

They are optimized away at compile time.

[gildor]

So, you need not a “kotlin vs java runtime benchmark” but rather benchmark that compares loops

[karelpeeters]

Go to tools > Kotlin > Show Kotlin bytecode and then if you want click decompile to see equivalent Java code.

[gildor]

also not sure that it make sense to compare using benchmark, just check bytecode

[vpriscan]

okay, thanks

[gildor]

Yes, exatly what Karel said

[gildor]

decompile to see equivalent Java code

be careful with it, it can be very missleading, if you really care about micro benchmarking you should read byte code

[karelpeeters]

It helps having them side-by-side to read the bytecode more easily simple smile

[gildor]

actually even bytecode is not enough, because this can be something completely different on runtime with JIT
