I'm not actually sure which comment I'd intended to reply to anymore (wrote it quickly on a lunch break!) - but, anyway: I'd agree the JVM is a bit faster than the CLR currently, but this is arguably because the CLR is more heavily tuned towards startup time (the reduction of), rather than throughput. They've invested more heavily into AOT compilation support (also in service of this goal) and compiler-as-a-service tech (Roslyn) rather than performance... perhaps this might change? Certainly the community additions to the CLR and the larger ecosystem eg ASP.NET Core have produced some notable performance improvements.

Also I'd say the CLR has more potential insofar as performance due to its design than the JVM does, but the JVM has received more attention in this area historically, so it's 'winning' currently despite this.
