The best C/C++ <-> Java application comparison I can think of 
off-the-top-of-my-head would be uTorrent and Azureus (That's the actual 
Azureus, not Vuze - I don't care what the creators claim, Vuze is a 
*completely* different program.)  uTorrent and Azureus are nearly-identical 
in purpose, features and UI. uTorrent is smooth as silk. Azureus is a bit 
sluggish (certainly not Eclipse sluggish, but no where near uTorrent). 
uTorrent is C/C++. Azureus is Java.

And just overall, the majority of responsive, non-bloaty software I've used 
*has* been natively-compiled stuff. The majority of sluggish, bloated 
software I've used has been some form of interpreted code or VM, such as JVM 
or .NET. So even if we're comparing apples and oranges, if Farm A makes 
apples that are usually juicy and sweet, and Farm B makes oranges that 
usually aren't, I'm going to feel fairly confident in saying that Farm A 
kicks Farm B's ass.
