"-server

"JVMs based on Sun's Hotspot technology initially compile class methods with a 
low optimization level. These JVMs use a simple complier [sic] and an 
optimizing JIT compiler. Normally the simple JIT compiler is used. However you 
can use this option to make the optimizing compiler the one that is used. This 
change will significantly increases [sic] the performance of the server but 
the server takes longer to warm up when the optimizing compiler is used."
