Kettle startup times in versions 7.0, 8.0 --- and 8.1 ?

There is a good article about Pentaho startup time, and how to speed it up at:

The 'remove plugins' method works for Pentaho Data Integration (Kettle) versions 7.0 and 8.0, but no longer apply to version 8.1.

Has anybody done work with startup time in Kettle version 8.1?
