Obviously it depends on a bunch of factors but -- not on my machines. They are all with Intel and AMD CPUs and I don't use M-series Macs.

Never saw an instantly starting JVM in my life though.

Java runs a Hello World, cold, in a packaged JAR, in about 40ms. What you've seen isn't JVM startup but programs that do a lot at initialisation (like MS Word), as many Java programs like to do (because they often expect to run for a long time, so they don't care about startup time).
