Core Sync Constantly At 100% CPU Usage.

This still seems to be an issue. I am using a newer MacBook Pro running Catalina and I couldn't understand why my fan was always running high even when I was only browsing the web. I opened Activity Monitor and saw that Adobe Core Sync was bouncing between 99% and 100% CPU usage. I ended up force quitting Core Sync and within a few minutes my fan slowed down and my MacBook started to cool down. 

Adobe support: Not only is this annoying, but it is also potentially decreasing the lifespan of people's computers. The effect of running a processor at 100% constantly will, over time, began to degrade the processors through a process called electromigration.  Adobe Sync is destroying people's computers. This needs to be fixed. 

Electromigration is when metal atoms wander into the dividing layers on a microprocessor. It is caused by the combination of electricity and heat. Processors are designed to run within certain heat and electrical specifications, and if run at higher heat and/or electrical specifications, electromigration may occur. If this occurs to a great degree and enough metal atoms wander off of the lines in a processor, they may permanently ruin the processor by thinning a connection so that it does not work effectively, or even making an electrical connection where one is not intended to be. Overclocking and raising voltage supplied to a processor increases the risk of electromigration.

I still see this issue occasionally on my macbook pro. It usually right after updating some adobe apps. If I open all the apps that were recently updated, then close them, the problem goes away. I just validated this after the latest 2021 update.

For anyone on a Windows PC, I learned that CC has trouble with folders that contain many files: once I consolidated these folders into ZIP files, that impacted the performance quite positively. And every time I progressed into reducing the amount of folders with many files, performance improved even more. 

Still, for a very brief moment, CoreSync and Explorer together manage to gobble up ~50% of CPU (which causes my CPU to be used 100% for that brief moment), but at least I do not have to wait that long anymore.

Though that this works, it also feels like a workaround to me. I still think that this is a problem.

Same issue here. Since 2018 I have always had this issue. No exceptions. On Windows, high CPU of CoreSync is paired with high CPU of Explorer.exe. When I turn on my Surface Book or wake it up from sleep mode (not quite a low-end laptop, I would say), I have at least 5 minutes of constant 100% CPU usage dominated by CoreSync and explorer. I did many things. Changing CPU priority, changing upload/download limit for Creative Cloud, reinstalling Adobe CC (from the official website), reinstalling Windows... Nothing works. Leaves me at the only conclusion left: it must by CoreSync in combination with explorer. Please do sort it out.

Hi Derek,

Sorry to hear about your difficulties.

A few questions and things to test:

• Would it be possible to capture and screen a screen shot from Activity Monitor?
• Are you actively syncing files when this issue is occurring?
• Does unchecking the sync on/off option in the Creative Cloud app preferences make the CPU use go down?

• Also, just to confirm, what version of the Creative Cloud Sync is listed in the preferences?

Please get let me know when you get the chance,

Thanks,

- Dave
