Switch vs if ?

[Laurent Bourgès]

Hi,

I ask you as you are the hotspot & jvm performance experts.

Do you know if hotspot prefers if over switch on integer values (profiling
hotspots) ?

Is it worth to order integer cases with higher probability first or not ?

How to optimize such if cascades ?

Cheers,
Laurent
