Hi,

I'm working on macOS launchAgent based project, and using 3rd party code to upload big files to remote server.

from time to time, I see that the upload rate is very slow and when i try it to use command line tool, the paste is much faster.

Therefore, I believe that launchAgent based processes, may get low priority in using network bandwidth compared to foreground tools. I wonder if there's anything I can do on the process' info.plist file to get better prioritization on network resources.

Perhaps I need to call the file uploader/downloader from dedicated XPC helper tool, but I prefer doing it from the same process.

Thanks !

is it possible that launchAgent get less bandwidth when other foreground processes compete on the same resources ?

Yes. It’s also possible that it’s getting less CPU. See the description of ProcessType in the launchd.plist man page.
