Rhino load speed update

Rhino
1

Here is my timing log when opening Rhino. After I’ve opened one, I’m OK for an hour or so.

RhinoCAM loading has a huge effect, but there must be more to it. Surely I’m not the only person with this?

My laptop is relatively new and higher specced.

Would appreciate any input!

RhinoCAM is a known huge loading slowdown.

Those 3 stand out to me. I’ve no idea what the first one is - hopefully @stevebaer or one of the other brains will chime in - but here the “after log events” is just over 0.5 seconds. Also, I have no idea why your Cycles takes that long to load - here it’s just over 1 second. As for RhinoCAM that might be normal. It might be worth asking MecSoft what kind of load times are expected?
Have you tried disabling RhinoCAM and see if it helps with any of the other load times?

Hi Adrian -

I’m assuming you are running Rhino 8. Could you post your SystemInfo data?
Also, does Rhino 7 launch quicker on that same system?

What happens after that?

Hi @wim , thanks for the message.

System info below… Yes I am running Rhino 8.

I have Rhino 7 installed, but since moving to 8 it doesn’t want to pick up the license for 7 any more. I do recall that 7 was slow also. I can persist with getting 7 running if that will provide helpful information.

On my comment about “OK for an hour or so”, sorry that wasn’t very clear.
If I’m using Rhino and open a fresh Rhino session, it can open up in 15 seconds, which is great.

However if I don’t have a current Rhino session open, or haven’t been active in Rhino for some time, I then get the situation per my original post where it can take 3-5 minutes to open Rhino, whether an empty session or a pre-existing Rhino file.

It feels like either it is stalling with license verification, or there is some fight going on with a firewall. However I have turned off Windows Defender and firewalls on my PC and do not run any virus protection software on this PC either. At work we do have a Fortinet system for cyber protection and VPN access, but the loading issue is still a problem if I’m working from home.

Thanks for taking a look, and I’m really keen to get to the bottom of things as it is super frustrating!

Regards,

Adrian

Thanks @Normand , Rhino only takes 12-15 seconds when I’ve had it open and using it.
It seems to slip into some sleep state when not used for some hours, or when I’m opening my first Rhino session.
I’ve provide more info in a separate response also to Wim.
Regards,
Adrian

Perhaps you could try adding C:\Program Files\Rhino 8 to your exclude list for your security software, be it the integrated Windows one or any other you use, then compare start times.

Thanks @nathanletwory , I thought we were on a winner, but today it slowed up again.

Updated timeline below and pause after log event. Seems odd @wim ?

Adrian
