. Why three times slower ?
q
That's not it because the lambda for apply is inlined. @tateisu Can you try a JMH run?
d
You're not taking into account jvm warmup.
t
There was almost no difference in the measurement using JMH.

@tateisu send JMH code?

Surprising indeed. Maybe the extra variables have something to do with it. Can you try replacing the value with an actual HashMap?
