High CPU usage on OS X

Hi Jim,
Did you happen to send another diag when this was happening? I would like to take a look.

Thanks!

Hi Tony,

I hadn’t, but just did on startup – it is doing its thing (I again shut down Evernote).

Thanks,

Jim

Heh… yeah this time it was massive Firefox cache activity. We really just need to exclude ~/Library/Caches from monitoring. I will see what can be done about this.

Hello,

I have the same behavior.

There is a fix to the problem?

Thanks

Hi!

I have the same issue - always have - are there any workarounds?

Thanks,
Justin

Hi @jhoff33,
Generally elevated CPU is either active syncing, the background scanning process that happens on odrive start-up and periodically afterwards, or excessive file system events from the OS. For scanning, the larger your local odrive structure, the more work odrive needs to do to keep it all in sync.

  • For active syncing, you really just have to wait until it completes.
  • For scanning, unsyncing folders that are not needed can really help to reduce the work needed to keep everything in sync on local and remote
  • For file system events it is generally bursts of activity, so I wouldn’t expect sustained CPU load. If this could be the cause we can test by turning off events and seeing if it makes a difference.

If you send a diagnostic from the odrive menu I can take a deeper look.

Hi @Tony,

Thank you for the response! I have just submitted a report. I’m not sure how I can identify it for you - you can find it by my account name? Please let me know what I can do to assist! Indeed this only happens when I first startup odrive. The cpu goes crazy for about 15-20 minutes each time. If this is expected behavior I suppose there’s nothing to be done but I would be interested in your thoughts.

Thank you again!
Justin

Hi @jhoff33,
I don’t see anything that raises a red flag in the diagnostic. There is some routine scanning, but your folder structure isn’t very large and the scanning isn’t lasting all that long. There is a fair amount of filesystem activity, and that could be increasing CPU.

The next time you see this happen can you note the time it starts and stops (if possible) and send another diagnostic?
How often would you say this comes up?

Hi @Tony,

Thanks again for the prompt response. I have just submitted another Diagnostic.
For your questions:

  • I started odrive at 10:15am Eastern Daylight Time (today, May 12th), CPU activity increased immediately and stopped at about 10:35am EDT (give or a take a minute).
  • This happens every time, without exception, when odrive starts. It’s for this reason I no longer have odrive start on system startup, as it tends to slow down the startup of other services. I start odrive when I need it, which is sometimes daily, sometimes not.

I do tend to reboot my computer frequently for various reasons, so unfortunately this problem hits me a lot.
I love the software, and I am grateful to have been grandfathered in so I get the unsync feature for free, it’s a wonderful feature!

Thanks again for any assistance or advice you can provide!

Hi @jhoff33,
I took a look and odrive was doing its extensive initial scanning on startup. There is always a flurry of activity on startup as odrive checks every nook and cranny to make sure everything is as it should be. Generally I don’t expect it to be as long as you are seeing here unless the structure is extensive, but there can be other factors at play that can lengthen the time and impact.

In any case, it isn’t anything I would call “abnormal”. We run hot on startup, unfortunately. There was a post by another user regarding setting the priority of the odrive process. It’s not ideal, but it could help if you find that odrive slows other things down on startup: Decrease CPU priority so ODrive doesn’t interfere with other processes

Hi @Tony,

Understood, thank you again for checking it out for me, I do appreciate it.

Sadly I have this problem too. odrive churns and churns using 53.6 Watts on battery 95.8 degrees F fan blowing. It’s a bummer, I really wanted to love this. Maybe you can tighten the indexing system someday. Dropbox has it down, but they have a big budget…

p.s. This is on a MacBook Pro (Retina, 15-inch, Late 2013) running 10.12.4 (16E195) and odrive version prod 6296.

Hi @matthew.james.briggs,
The next major release we are working on will optimize this a lot, especially for large datasets.

That’s good news! What’s the timeline? Does the mac application auto-update? Thanks.

Hi @matthew.james.briggs,
This post is the best answer I have for information on the next major release:

It is likely that we will not auto-update the current release to the new one - at least for quite some time - because so much will have changed. Once it is available it will be announced via all of our channels.
