Hi all,
Looking forward to sinking my teeth in here. Just cranked up the WIP for the first time and nearly got whiplash from the startup speed. Really phenomenal!
Also, just looked at the “Edit” command line option for FilletEdge and nearly cried. It’s so beautiful. 
More to come…

That is nice isn’t it… I believe the reason is that third party plugins aren’t taking up start time to load. If you watch the bottom of the Rhino 5 splash screen as it starts up you can see how long certain plugins take.
Hi @brianj did you see my post at the other end of the spectrum?

I missed that one… but just replied. Thanks.
That is definitely part of the reason. We also put some effort in to making the core start up code more efficient.
