    Resolution: Won't Fix


I'd need to see concrete data showing that (un)boxing is a performance drag. Please reopen if this is the case, but tbh I don't see how to fix this as per my explanations...

> The JFR profiler is highlighting a significant amount of boxing and autoboxing, as the request is is treated as a {{long}} but this is used as an key for the {{Map<Long,Request>}}.
> We could try to either consistently use {{Long}} rather than {{long}}, or even better figure out an optimal data structure to replace the implementation of the Map to not require boxing of the keys.
