Houdini has always been a little slow to launch for us, about 1.5 minutes, but I kind of attributed it (with no real evidence) to the large python code base on the network that is added to the PATH environment variable. With 18, launch times are around 3 minutes. These times are with the Arnold htoa plugin installed. If the Arnold plugin is excluded, launch times are much faster.

So my question is, is there any way to get some kind of debug info on what may be causing these long startups? I'm impatient and think of all the stuff I could get done in those 3 minutes!

Thanks,
Karl

Hi Karl

We're experiencing same issues with a big'ish external python code library.

I also would like to know if there's a way to speed things up with the launch.

Thanks,

OCIO seems to be one of the culpits on our end. It's like 1-2 min VS 12s for a “naked” Houdini.
Depending on how your pipeline is set up, a package manager like rez might make sense in the long run.
