I have a mysterious process on my Macbook pro which I can't isolate which comes around every 5 seconds and interferes with my connectivity.
My ping history looks like this:

I can tell that this is local to my machine (and not the network) because these results don't change when I switch networks and other machines on those networks don't show the same intermittent stagnation.
I have closed every application that I can including the obvious background ones (Dropbox, Google Drive, etc.) but the problem persists.
At this point I'm at a loss as to how to pinpoint what service or process is doing this. I'm hoping someone has some remedy or third party tool I can use to isolate the culprit and shut it down.
