File saving slow again, but autosave is fast

Hello I know there are already topics about this issue but I decided to make a new post to catch somebody’s attention.
I’ve seen this Rhino saving extremely slow issue couple of times, and still don’t know what triggers this. Maybe Antivirus? This hasn’t been happening for a while but started happening on my new environment. Once this problem started happening, 1gb takes more than 1hour and 500gb for 30mins. Regardless of whether it is a network drive or a local drive, normally 1gb saving should be done in less than 10mins if there is no problem.

In my case, it’s slow even if I’m saving files to a local drive.

But, I found something that might be interesting… Autosave is fast. It’s very fast. There is no slowing down. I assigned Autosave to Ctrl+S and will see this can be a temporary remedy.

Does this, Save is slow but Autosave is fast, give somebody a clue of what’s happening?

If I remember correctly, the default setting for Autosave is to save only the 3d data without the meshing of the NURBS models (exactly what the “Save small” command does), so this is why it’s considerably faster than the regular save. If you experience such massive delay in saving, I recommend you to use “Save small” as an alternative for the moment. One downside of “Save small” is that upon opening the file for the first time you will have to wait some time for Rhino to calculate the rendering mesh of all the models visible in the scene.

Slowdowns in saving models usually happen when the file contains materials with embedded textures.

Another problem is caused sometimes when certain objects have applied custom render mesh.

Hi - one hour for 1 GB doesn’t sound right, no.

What does “new environment” mean?
Could you run the Audit command and post the result here?

HI, I’m already using SaveSmall (and assigned it to Ctrl-S) and this slowing down issue occur still.

“new environment” meant I moved to a new office and got a new machine.

Hello - Autosave saves to the autosave folder, which is typically on the local hard drive - is the regular Save (i.e. file location) on a network drive?

-Pascal

No, I tried saving to the AutoSave folder, a lot slower than when saved via “AutoSave”…

Also I tested place the AutoSave folder to my Portable HDD, and to my desktop. Same.

Hello - can you please run a second audit command, Audit3dmFile and post the results?

-Pascal
