Maybe too many. Sometimes we are looking for a specific option or the &ldquo;magic&rdquo; one that can give a serious boost in an application. Unfortunately, I think that magic option may not exist! However, some can help you for optimizing your application or for tuning some of its parts.</p> <p>To find the complete list of options you will find in the <a href="https://github.com/openjdk/jdk/blob/master/src/hotspot/share/runtime/globals.hpp" target="_blank" rel="noopener noreferrer">globals.hpp</a> file from OpenJDK sources. However, the <a href="https://chriswhocodes.com/vm-options-explorer.html" target="_blank" rel="noopener noreferrer">VM Options Explorer</a> , also <a href="https://foojayio.github.io/website/command-line-arguments/openjdk-11/?tab=alloptions">integrated neatly here into foojay</a> , can help you to navigate through the list.</p>
