Slow Load Times

I have been encountering increasingly lengthy times to load Rhino files. In some cases files will load immediately and others it will take several minutes. The load time is unrelated to the file size. I can have a 70MB file load instantly and another 3MB file take five minutes.

In all cases I am reading from a local disk.

I am wondering this is being caused by file versioning.

Hi John -
I can’t say I’ve heard about this before.
Would it be possible to post that 3MB file that takes 5 minutes?

I just uploaded one to the suppoort web site. I was able to do all the steps to upload and it’s still loading on rhino here.

Hi @miano,

I can open your file in Rhino 7.19 with do delay on Mac and also Windows. I have one thought in addition to your versions idea. I am wondering if the layout Page 1 being active is a factor on your Mac and macOS. See if not having a layout view active when the file is saved changes how fast it opens for you next time. Also try the file location in a non-iCloud synced folder as a test too.

Reply back here or on the tech email to let us know what you found. We’ll probably need your current SystemInfo too if you need more help.

I does seem to load a lot faster when the layout is not active.

I will keep a look for that with other files that are slow.

I am not synched to iCloud.

Okay, what macOS are you on? SystemInfo?
