In this blog, we will discuss how Server JRE differs from Client JRE. It will also give insight as when to prefer Server JRE over Client JRE or the other way around.
As per the second chapter of ‘The Java HotSpot Performance Engine Architecture‘: The JDK includes two flavors of the VM — a client-side offering, and a VM tuned for server applications. 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. These differences include the compilation policy, heap defaults and inlining policy.
To understand it in a nut-shell read the following descriptions:
Server JRE: It is used to deploy long-running java applications on server. It provides the fastest possible operating speed. It has been specifically fine tuned to maximize peak operating speed. It has highly aggressive algorithms to optimize the runtime performance of java application. It also includes variety of monitoring tools.
Client JRE: It is used to run java applications on the end-users systems. It contains everything to run the java applications. It can start up faster and requires a smaller memory footprint.
