Every time I boot and log in to the Dropbox program, it would use 40% - 60% of CPU on my computer, even when there are no files to be synced. Why is Dropbox using high CPU? Any ideas or suggestions? How can I make Dropbox use less CPU?
CPU, short for central processing unit, is arguably the most important component of a computer. CPU usage can be an indicator of how much stress the current central processor is currently undergoing. If Dropbox takes up most or all of your CPU usage or memory, not only will Dropbox be unable to work, but your computer's performance will also slow down, affecting the operation of other programs.
When you sync files with the Dropbox program, several processes will be used to index, store, and update files, which may take up CPU on your computer. Typically, the more files you sync, the more CPU/memory Dropbox may use during synchronization. Besides, files you save in the Dropbox folder on your computer will occupy local space, causing Dropbox heavy CPU usage on the computer.
If the syncing files are opened by another application or cannot be uploaded to Dropbox correctly due to permission issues, it can lead to excessive load on Dropbox. Also, since Dropbox does not work with network share file systems, installing the Dropbox folder on a NAS device will cause Dropbox using too much CPU as well.
When you're not running many applications, your CPU usage should be low, and ideally, everything should be running smoothly. If Dropbox uses high CPU when indexing or syncing files, you can try the methods below to fix Dropbox high CPU usage on Windows 10 and Mac. In the following, we will take steps on Windows computers as an example to show you detailed guides.

If files are being used by a third-party program when you add files to Dropbox, this will cause Dropbox to conflict with this program and eventually lead to excessive CPU usage. Your security software may also conflict with Dropbox and cause the same situations to occur.
Fortunately, you can resolve this issue by ensuring that files are not in use and are synced properly without permission issues, etc. Also, you could isolate third-party applications that make Dropbox consume a lot of CPU and memory resources from Task Manager.
When there are more than 300,000 files in the Dropbox folder, the Dropbox app’s performance starts dropping.
