Why does Grasshopper on R8 takes a lot more time to open a script compare to opening the same script on R7? I am getting something like 1 minute vs 8 seconds! Metahopper said certain cluster and python script are the issue but first they have no internalized input data so they should not compute and second deleting them will not make it faster because it somehow makes the next cluster/python component become the culprit so it is like chasing its tail.
Not just that but the interacting is also slower, especially exiting out of a cluster (without saving) takes 5 seconds compare to almost instantly on R7.
Yes I have a massive script ( > 12000 components) but it was much better on R7. No I cannot upload it as it requires our extensive plugin + library set up that is quite complex. I always have auto-save disabled for GH and my hardware is definitely not the issue here (posted below).
R8 is set up to run with .NET Framework due to 3rd party plug-in requirements.
I am probably not gonna achieve anything from this post but then what else can I do?
