(OS X) Dropbox consuming a lot of CPU whenever any file or folder is changed anywhere
On my OS X 10.9.5 system I'm seeing Dropbox consume CPU whenever anything on the file system changes, regardless of whether the changed files or folders are in the Dropbox synced folders. The CPU usa...
I have the same issue: Every time I make any operations which modify a lot files anywhere outside the Dropbox directory Dropbox just consumes 100% CPU. I can reproduce this issue easily by just extracting a very large tar file (e.g. the Linux kernel sources) somewhere outside the Dropbox directory: Even with a completely empty Dropbox directory (that obviously contain no symlinks) I get a very high CPU use of the Dropbox process even though not a single file in the Dropbox directory was modified.
I attached DTrace to the Dropbox process and can see it making thousands of system calls per second when I extract the tar file somewhere outside the Dropbox directory:
Dear Dropbox developers, are you *sure* you're not listening to *all* filesystem events which happen in my user's directory? Because to me it completely looks like that and is the reason I get such a high CPU use when I make heavy filesystem operation which shouldn't bother Dropbox at all.
