(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 recently got a bigger SSD on my MacBook Pro wanting to be able to finally have my whole 400GB Dropbox local, but this is proving impossible. The Dropbox process is randomly grinding my laptop to a halt with the fan spinning up full tilt. I've been zipping folders of older stuff to try to reduce the file count (somewhere around 130K files). This sucks.
Additionally it took about five days over my gigabit home network to do LAN Sync. That makes no sense. The whole time it said something like "2 Hours Remaining". Again, with the CPU going 100-150% with the Dropbox process the entire time.
I love Dropbox, but it's really not scaling properly at "pro" level.

9 years agoHey Nathan & Shelle,
Thanks for reaching out on the Dropbox Community! Let's follow some steps together to improve syncing.
As a first step, could you have a look at this article and see if any of the cases mentioned there applies to you? The best course of action would be to make sure that you've installed the latest stable version of the Dropbox desktop application on your device. If you aren't sure about whether you have used Symlinks, please have a look at the steps here:
#1. Open your Terminal app (Located at /Applications/Utilities/Terminal). You can also search for "Terminal" using the magnifying glass at the top of your screen.
#2. Copy and paste the following line into the Terminal:
(NOTE: If your Dropbox account is located on "/Users/JaneA/Dropbox", then fill in the command line as below)
find "/Users/JaneA/Dropbox" -type l -exec ls -lah {} \;
The above should give you a list of symlinks in your Dropbox folder and where they point to.
Hope this helps you resolve this issue!
Kind regards,
JaneA

I think this may have helped some. I have no links inside my Dropbox, but I followed the directions to update all the file ownerships and chmod settings. It indexed for probably 2-3 days (140K files), but Dropbox finally settled down after that...

This is the only thing that worked for me:
http://www.michaelcarwile.com/throttle-dropbox-and-other-app-cpu-usage/
Dropbox (and other apps) has a tendency to use every bit of CPU it can, especially when starting up. On Mac (with Homebrew installed), Dropbox (and other apps) can be throttled via a tool called cpulimit.
Install cpulimit:
brew install cpulimit
Get Dropbox’s Process ID:ps aux | grep Dropbox user 19628 104.7 2.3 xxxxxxxx xxxxxxxx ?? R 4:07PM 15:47.12 /Applications/Dropbox.app/Contents/MacOS/Dropbox
Run cpulimit with the -p flag using the process ID:cpulimit -p 19628 -l 40Note: That’s a lowercase L (for limit) and the last number (40 in this case) is the percentage % of CPU you’d like to throttle the app to.
Also Note: cpulimit will output ‘Process xxx found’ and will continue to run until you kill it with <CTRL> + C

Just installed -- this is really cool, thanks... will be handy not just Dropbox. I might figure out a way to write a little script that can grab the PID for dropbox without too much trouble and start up. Will post back here.
