File access slowdown when working in project on remote disk



I'm finding that when I open a project on a remote drive, All file and debugging functionality slows to a halt. I don't think this is just a matter of slow network, as I can open files on the drive while working in a local project and there's no slowdown at all. Once I'm in a project on the drive though, that same file will take ~15 seconds to open. This becomes particularly frustrating when debugging functions, where it takes 15 s just to start the debugging. Any solutions?

update: the issue only seems to pop up once a shiny app gets launched. Running the app on the same project locally doesn't cause the issue, and closing the app/clearing everything from environment doesn't resolve it. Rstudio has to be relaunched.

update 2 : it's actually plotly that's causing the issue, and removing temp files / running / clearing all plots in history doesn't fix the issue. Launching the shiny app directly in a browser instead of through rstudio seems to avoid the problem.

There’s been some discussion of laggy-ness with projects on network drives:

I don’t know if this is the same as any of those issues, or if this is something else?

Some system information might be helpful...

There's certainly similarities in symptoms, but mine only begins once I launch shiny. It seems to actually be plotly that's the cause of the issue, but even after deleting all temp files associated with the plot the problem persists.
