In my initial post, I failed to mention the huge memory savings achieved by the standalone executable (in addition to the startup time savings).
Note that using *time* at the command line resolves to a shell built-in command. We can get more information from the standard Unix version of time: # JVM+UberJar > /usr/bin/time -l java -jar target/hello-world-0.1.0-SNAPSHOT-standalone.jar Hello, World! Goodbye... 1.20 real 2.47 user 0.24 sys 409 maximum resident set size (MB) 100469 page reclaims 3569 involuntary context switches # Static Executable > /usr/bin/time -l target/hello-world Hello, World! Goodbye... 0.00 real 0.00 user 0.00 sys 2 maximum resident set size (MB) 657 page reclaims 4 involuntary context switches So we see that the maximum RSS memory requirement *was reduced from 409 MB to 2 MB*. Yes, an improvement *over 200x!* Note also that context switches have been *reduced by 900x,* and page reclaims by *about 200x*. So, it is the combination of reduced startup time and vastly reduced memory requirements that make standalone executables ideal for short-lived tasks, especially in constrained environments such as serverless/lambda.
