I've noticed that the Windows Logos 7 program is using 25 to 40% of CPU usage when I have it open, but not actually interacting with it at all. The indexer is not running (finished indexing a while ago).

Is there anything useful that Logos is actually doing that is causing this CPU usage? I've attached a typical output from task manager. 57% CPU usage on my PC. Most of that is Logos.

This isn't just for a few seconds - the main process is permanently using 24 to 30% of the CPU just by the program being open. I've had it open for several hours and it is still using 25%+ CPU

(Windows 10, 1TB SSD with 750GB free, 16GB RAM, i5-6500).

Well, I just killed the "Media" window, and Logos drops to less than 1% CPU usage. But the Media window wasn't doing anything that I could see. It was just displaying  graphic. Those Logos CEF processes are now using 0 to 3% CPU now.

Is the Media window doing something all the time in the background?

I displayed the Media window by clicking a Joel bible background graphic in the "Media Collections" section of the passage guide.

Anyway now I know what window is causing the excessive CPU usage I can just kill it when I've got the graphic I need. The high logos CPU usage kept making the PC fans come on very loud to cool down the system, but it is all quiet now!.

Concur. I was getting 29% with Media open.

Jim,

Can you let me know what resources you have open, and a screenshot of what your layout looks like. It will help us reproduce this issue.

My layout. Small number of collections, active visual filters, links, parallel resources --> starts quickly.

Resources --> SBLGNT, Quran, DBL Greek, ESV, Bible Knowledge Commentart (BKC). Closing  them doesn't affect the issue!

Jim and Dave,

Could you do the following:

  1. Click on the gear on the home page.
  2. Turn each option off.
  3. One by one turn each conent source on.

Please let us know if you observe a spike in CPU usage when  you turn a specific source on.

Hi,

I tried that but apart from a few seconds spike when a new resource was turned on and the home page repainted, there was no real CPU increase after any of the options.

I am finding that the Media window does not always cause the high CPU usage. It doesn't in another layout I have for the sermon on the mount.

Conducted tests with Media off. Spikes of 12-15% after turning on each Content, but then settling back to 0%. After returning to my layout, Media  started at 6-7% and remained constant. But after going to Home Page, checking Settings and returning, Media spiked up to 32% and remained constant. Thereafter, Media would start and remain at 32-34%.

Dave,

Thanks for including this info. I was able to nail down the steps that cause this and have created a case. Thank you for your patience in nailing things down.

It wasn't particularly scientific, but glad you were able to use it.

I'm having a similar issue with CPU usage when I'm doing a Bible passage list. As you can see in the picture, I have closed all Logos windows except for the passage list, and Logos is still taking around 30% of my CPU to look up a passage. It will go down to 1-2% but every time I type in a passage (ie. 2Ki2) it goes up to 30% and my computer slows down. Each time Logos also temporarily says "not responding" but then works fine. I am running Windows 10 on a MS SurfaceBook.

I can't reproduce this in Logos 7.10. Does it make a difference if you disconnect your dual monitor setup?

Jai, 

Hi. Unrelated question: how do you like running Logos 7 on your Surfacebook (I assume is not Surfacebook 2)?  I'm considering getting one but how Logos runs on it is a key factor.

Hi Ross,

I'm running it on the original SurfaceBook - but with maximum (for the time) specs - 16GB RAM, Intel i7-6600U CPU (and of course they all have SSDs - mine is 500GB)

I find Logos generally runs quite well (other than the problem as noted above) - most of the time I use it plugged into an external monitor and keyboard while doing so, as I find I need more screen real estate.
