Primarily this comes down to previews being enabled, albeit not exclusively. If you disable previews I'm sure things will behave better, there'll likely still be stuttering though. The problem here is that POSIX IO APIs are synchronous in behavior. So by mounting a remote file system you essentially make all software address it through those blocking calls and they then can take aaaaages to finish. The blocking API call is subject to network latency/bandwith constraints and the remote's IO latency/bandwith constraints, and that is why you get intermittent blocks. It's simply waiting for replies. This is always a problem with mounted remote file systems, but in this case its made more prominent because your file copy causes an exhaustion of one of the constraints making the requests take so long that you can notice the UI intermittently locking up.
