Are there any fixes for slow saving in Rhino 8? I have a brand new beast of a machine, huge nvme drives, all my other apps save extremely quickly and fast (photoshop, meshmixer, Zbrush, etc. Why is Rhino taking forever to save a 300MB file??
Extremely unpleasant working on rush deadlines with this issue.
Please fix, thank you.

Would you be able to share you machine specs and provide the file so one of our developers can test?
Turn off the default file ācompressionā. The ppl in charge think it makes more sense to have it on (by default), but it doesnāt ā harddrive space is cheap in the 21st century. It only causes everyone to think the new Rhinoās are slow, and no one ever says anything about the silly secret hidden default āfile compressionā obstruction ā you have to dig to find the secrets, for some if not most, it took yrs before it was discovered. Imagine all the time that was waisted saving files and twiddling thumbs, and thinking the new Rhinoās were slower than the old Rhinoās.
Imagine all the users that gave up on the new Rhinoās, that didnāt realize it was some hidden setting somewhere that was the culprit the whole time.
Imagine all the harddrive space that could have been purchase cheap to compensate for the lost time waiting for saves.
File compression should be off by default ā period.
Make sure this is unchecked:
If you run out of harddrive space, just buy more. Time is money.

@carvecream does this fix it for you?
Very slow when file compression is enabled

Disable it. For the most part, unless your disc space is very limited, there is no reason to have it on. This is not a V8 problem, it was already true in V7.

Does this option actually hooked in Mac R ?
it is there in advance, but I disabled it [did a rhino restart made a small change and resaved
file size remains the same. [it a big file]
- didnāt actually see a noticeable lag in saving, but I do have a long wait when rhino open the file.
[wishful thinking about it having to do with the decompressing ā¦]
thanks

oh good lord how did I not know about this all these years. crimminy.
but hilarious that it takes 4 minutes to compress a 900mb file to 500mb, thatās seems broken in itself!! 
but iām now very happy with fast saves. Thank you @lander and everyone else.

Yeah but V8 turned it back on, so glad I stumbled on this thread cause it shoulda been off already

Just experienced this after v8 upgrade. I can confirm that by unchecking ācompress in saveā does speed the save process up. Thank you.
I hope McNeel could turn this OFF by default.

Saving withouot compression is significantly faster! From one minute to one second!
(on a 300-400mb file)
Still, is it possble to improve the compression algorithm to make it run faster?
Many use the coud to sync files, so smaller files means less cloud space and less sync time.
Thank you!

Whenever I use WinZip or 7Zip to zip large files, I keep wishing that this would go faster. If you invent a way to do this and want us to implement that, let us know.

Thanks for your reply @wim
I could suggest compression running in the backgound, so Rhino would still be usable while the file gets compressed.
Compression progress can be shown in the bottom right corner.
In other words, users can Save or Save compressed while Rhino is still usable.
About compression algorithm, PLZIP algorithm, for example is multi-core. But Iām not sure if it makes a big difference since saving has to do with dynamic memory speed.

well, what can I say, these topics are related, they gathered much attention, and have been on the list for 5 yearsā¦ so, maybe itās time
