The Client VM compiler serves as an upgrade for both the Classic VM and the just-in-time (JIT) compilers used by previous versions of the JDK.
It is intended for executing long-running server applications, which need the fastest possible operating speed more than a fast start-up time or smaller runtime memory footprint. These differences include the compilation inlining policy and heap defaults.Īlthough the Server and the Client VMs are similar, the Server VM has been specially tuned to maximize peak operating speed. These two solutions share the Java HotSpot runtime environment code base, but use different compilers that are suited to the distinctly unique performance characteristics of clients and servers.
The JDK includes two flavors of the VM - a client-side offering, and a VM tuned for server applications.
This is really linked to HotSpot and the default option values ( Java HotSpot VM Options) which differ between client and server configuration.įrom Chapter 2 of the whitepaper ( The Java HotSpot Performance Engine Architecture):
