I've been having issues with my Mac's performance lately and finally tracked it down to the Salesforce Files app installed. The Folder Actions Dispatcher process was growing to 20 GB of memory used! It looks like Salesforce Files had attached folder actions to Trash and some sort of bug was causing huge memory usage. I ended up deleting the app and then removing the Folder Actions. Things are much happier now.

Anyone else noticed a similar issue? I'm on Yosemite.
