SaveACopy extremely slow

G’day McNeel,

Just used SaveACopy command for the first time and it is mind-bogglingly slow. 270MB file, saving to a NAS, normal save takes a little while (15 seconds or so), but this is pushing 2-3 minutes already with SaveACopy.

Anything I should look for in the file that could be causing this? I think it is a bit large due to some legacy textured meshes from scans, but those have been deleted and purged, however the file size is still a bit large.

cheers,
Nick

I’m also experiencing this. Even when it’s a 30mb file it takes upwards of 10 minutes!

I hate to reply to only amplifying the echo chamber but hopefully, the more people reply the more traction this issue will gain!

Bump…this is frustrating.

I’m still having the same issue

Using Rhino 8 on Win11

Seems to be that it’s not “saving small”? I get similar slow results and massively inflated file size.

The whole concept of saving render meshes in the file just needs to go away completely everywhere in 2025, this is a relic that made sense in V1 days.

Hi all -
I’m not able to repeat the behavior that is being reported here. SaveACopy is fast and the resulting file is the same size as the original.

Can anyone here provide more details, a model, SystemInfo?

SaveACopy is not supposed to save small.

G’day Wim,

Some extra info…

Simple 2D (curves, dims, etc.) files don’t seem to have this problem.

Saving locally doesn’t appear to have this problem.

3D models (surfaces, solids, meshes) do have this problem when saving to a network drive (NAS).

cheers,

Nick

Hi @NickB,

Is this enabled?

Saving to network storage will never be as fast as saving local. Files end across a wire (or air) are packetized and a whole lot of checksums and security bloat are added. If it’s really slow, save local and then copy to your NAS using Explorer.

I’ve never used it before, but the test I ran (on the WIP)did not SaveSmall judging by the file size.

Thank you, Dale.

Yes, this is set.

I understand saving over the network (CAT5, not WiFi) will be slower, but all my files are on the NAS and it is much slower than a typical save.

Hi @NickB,

All network storage devices, including traditional file servers, have security, encryption, and compression settings. You might poke around and see what you are comfortable turning off. Otherwise, do as I suggested - save local, copy yourself.

All “Saves” and “Save As” are to the NAS, but only Save A Copy is extremely slow.
