i am finding this as well.
as in it feels like its not a simple ON or OFF issue, but incremental (or relative to file size) issue.
I have posted in detail above, but my “original” file was 64MB, deadline will take about 20+ min to launch HOUDINI.
i removed nodes to get the file down to about 30MB, deadline will take about 10min
and when i bring it down to about 10MB, deadline will take about 3 min to launch.
the filesize to load time does not seem “linear” but definitely has some kind of relationship.
