Real differences between “java -server” and “java -client”?

I've seen the argument "-server" used as a command line argument for java.exe:

java.e开发者_如何学Pythonxe -server MyClass

but no matter how hard I searched the internet I found no documentation as to what exactly it does. Can anyone explain?

-server

Select the Java HotSpot Server VM. On a 64-bit capable jdk only the Java HotSpot Server VM is supported so the -server option is implicit. This is subject to change in a future release.

Basically, the server VM does stuff in a different way to the client VM. It has different styles of garbage collection, and it may take longer to load up but generally has higher throughput.
