Hi,
does anyone know how the performance of a BasicEMap compares to a HashMap? I mean mainly the speed of get()-operation?

Thanks

Joel

Joel,

I've not done a details analysis but they should be quite comparable.
I'm sure HashMap has seen more performance tuning that has gone into
BasicEMap, e.g., better collision handling. In any case, it's hard to
imagine that the performance difference would become a significant
performance concern in a larger application.
