I'm baffled by the logic, but I can see the tradeoff.

Wikipedia ``HotSpot'' article:

	In Sun's JRE, it consists of two interchangeable versions, one called
	Client and the other Server. The Client version is tuned for quick
	loading and compilation of essential classes and methods only. The
	Server version loads more slowly but puts more effort into producing
	highly optimized JIT compilations that yield higher performance.

Calling them "client" and "server" is confusing.  In some applications you
definitely want the behavior reversed: client is more responsive because it
deals with the human user at the expense of precompilation overhead.  Server
restarts are faster at the possible expense of reduced runtime performance
(the average server isn't CPU bottlenecked).
