This is something I’ve also noticed with SketchUp moreso than other similar software…exponentially slower copy & paste actions as file/object size increases.
It will work, eventually.
yes there are workarounds - helpful of forum users to suggest - but ultimately escaping the fundamental issue, which is the Copy+Paste speed is actually very slow. AND it has No Escape/Cancel function so you may be in for a Long wait (coffee break) before you realise what you’ve done.
It’s not the hard drive, it’s Sketchup packaging and streaming data to the clipboard. the Copy operation stresses the CPU, not the hard drive or RAM. Most of the CPU energy is directed to SKP app, not Windows System process.
A few things to try but unlikely to do much:
There might be some windows 10 settings worth checking… windows 10 had a clipboard update in October 2018, but enterprise users didnt get it…not sure if that’ll help (I dont have it).You should be able to search Clipboard after clicking on Settings if you have it. It might have a cache size limit or offer a location for cached data.
You can also manually Optimize the SSD drive if it isnt set to Automatic. (click on this PC then then drive icon, then Optimize (which is the new term for defragging).
Virus scanning software can interfere with the clipboard - anything set to “on demand” scanning will really slow down copy & paste. Try disabling that.
I have yet to try an NVMe drive, but that’s my next step. Will report back if i see a significant increase in copy+past speed, but I’m doubtful.
