One snapshot shows a total EQ pause of only 75ms, much of that in class (or rather, resource) loading.

The other one shows an EQ pause of less than 3s, again largely in class loaders (some also in JavaFXProjectUtil), but classpath scanning was also proceeding in parallel and this can be expected to saturate I/O.
