Legal JVM dopes for your apps
This talk explores how to boost application performance and hardware utilization without code changes, by leveraging JDK innovations like Leyden, CRaC, Lilliput, Graal JIT, native images, buildpacks, and virtual threads. It outlines their benefits, trade-offs, and when to use them, enabling future optimizations with minimal resources.

One reasonable desire is to speed up existing deployments without affecting code and diagnostic tools. Too many resources are spent on profiling, optimizing, and updating applications. At the same time, we need to improve hardware utilization, and frameworks and runtimes are reaching the end of their lifespan.
There are several JDK pills that help further improve existing applications without immediate re-development. Examples are OpenJDK Leyden, CRaC and Lilliput projects; Graal JIT, client VM, native images, buildpacks, virtual threads and fused JDKs. Let's study what aspects can be improved with their help, how and under what circumstances it makes sense to use them. For each one there are measurable profits and trade-offs.
With free development resources and budget savings after doping, teams will be ready for more complex optimizations and migrations without tearing the flesh.
