Rhino slow to open

Rhino
1

Hi everyone,

I’ve been dealing with a persistent issue across Rhino 6, 7, and 8, and I’m hoping there’s a solution.

Whenever I open Rhino, it takes several minutes to start, even with an empty template. There’s no indication that anything is happening on screen, which often leads me to double-click the icon again, thinking it didn’t register. Eventually, Rhino opens, and sometimes I end up with multiple sessions.

I’ve tried using the /nosplash option after the .exe to speed things up, but it doesn’t seem to help.

I have RhinoCAM installed and recently started a trial of SimLab, but the problem existed long before these plugins were added. It seems something changes over time after the initial installation that causes this delay.

I’m wondering if anyone else has experienced this issue and how they resolved it.

I’ve included my system info below.

Thanks!

Adrian

Try starting Rhino with the stopwatch flag and post your results here. Here’s a discussion of the flag

Thanks @stevebaer ,

I’ve copied that below.

It does look like RhinoCAM is making things worse, so I may need to look at disconnecting that when not in use somehow.

I’d be interested to know if the rest looks normal.

Thanks again, Adrian

Its strange that creating/loading a settings file takes 7 seconds. This indicates that you have some problems with IO operations. Either a broken disk, another application performing heavy IO operations, anti-virus or networking is causing this. I would not suspect a Rhino issue here. You rather experience the symptoms of it. A plugin might also serialize/deserialize config files.

6

We do know that applications like Windows Defender can interfere when an app like Rhino starts loading different libraries the first time as it seems to like to inspect what is being loaded. I’m not sure if that is the case here, but if subsequent running of Rhino starts much faster that may be a possibility.

7

Hi @stevebaer , thought I’d give an update. Defender has been taken offline.
Cycles and RhinoCAM seem to be the culprits.
Nearly 2 minutes total - feels like 5!
