@pmouawad , it was 2-3 seconds (before fix), and now it is 0.1sec (after fix) |
JMeter used to initialize all the components at the startup even in case the element was never used. This commit adds a shortcut for the well-known in-core components. User-visible outcome is the spashscreen no longer gets stuck for 2 seconds at 100%

On my machine menu initialization takes 2-3 seconds (2.6GHz, SSD, fully cached).
Most of the cases the time is spent in creating Swing components, however, that work is not needed to get the label for the menu.
Even though the proper approach would be to split metadata from the UI components, I think it is fine to have an intermediate solution.
Note:
TestBeanGuidoes not initialize UI elements, however, full bean metadata initialization still takes time (e.g. JSR223 elements query ScriptEngine for the list of available languages)
