Microsoft Teams slowing down workstation with no resource gain

Dear Vin,

Thank you for your update. Since you've already tried all available troubleshooting steps, the most effective way to get a resolution for this persistent Teams performance issue is to submit a support ticket directly to Microsoft. The technical support team will need to analyze the Teams support files (logs) you've collected to diagnose the problem thoroughly.

How to collect Teams Support Files:

• Navigate to bottom right corner of the screen, right click on Teams icon and select Collect Support Files

• Go to Downloads folder, you will see 2 folders as below. Please allow few minutes for the files to appear here.
• You can upload the 2 folders to the ticket for the technical engineer to investigate the issue. If the size are too big, kindly zip/compress them before uploading.

 Submit a Support Ticket to Microsoft:

Log in to the admin center, navigate to Show all > Support > New service request. Clearly describe the issue, including all the details you've shared with me here and any troubleshooting steps you've already taken. They have the necessary tools and elevated access to your Teams logs to thoroughly analyze the issue and pinpoint any underlying service issues or complex configurations causing this behavior. 

Once you have the Ticket Support ID (ticket number) from Microsoft Support, please share it with me via a private message here in the Microsoft Community. This will allow me to track the progress and ensure your case receives the necessary attention. 

To view private email options, sign in to Microsoft Community> use the email account that posted this thread information to Microsoft Community> > click Profile in the upper-right corner, and then select My Profile.  

Thank you for your continued patience. We are committed to helping you resolve this.

Kind regards,

Kai,

Here is what was done from the list you had generously provided to me.

1. Reviewed performance of teams while in a call I reviewed the CPU again and this time it was spiking throughout the call. Teams was going all the way up to 100% usage along with Microsoft edge.
2. Reviewed teams call health on teams while in a call that was utilizing audio video and screen sharing. The values for this seemed to be okay with little fluctuation.
3. I have gone through updated and verified versions of specified drivers. I also ran a scan/stress test of the processor
4. Power Managment Settings are set to high performance.
5. I was unable to review the antivirus item as of right now but am working on this one.
6. I performed the feature disabling to have the call run at minimum but am still experiencing spikes.
7. reviewed event viewer while in the call and with little errors in there none pertained to Teams

Dear Vin,

It has been a while and I am writing to see how things are going with this issue. Have you had a chance to check the replies provided? Any update would be appreciated.

Dear Vin,

Thank you for posting in Microsoft Community.

I understand how difficult it is to have Microsoft Teams slow down your workstation, almost to the point of freezing, especially when your hardware is robust (48 GB RAM, 1TB storage, i7 processor) and resource monitors show normal usage. This often suggests a hidden bottleneck, conflict, or network issue rather than a simple overload.

You've already tried excellent steps, including hardware acceleration toggling, cache clearing, and reinstallation. Let's dig deeper with a more focused approach.

1.Detailed Performance Monitoring (While in a Meeting):

Task Manager - CPU Cores:

• Open Task Manager (Ctrl+Shift+Esc), go to the Details tab.
• Right-click column headers, select "Select columns," and add "CPU usage" and "CPU (total cycles)."
• Sort by CPU usage. Look for Teams.exe or ms-teams.exe consistently consuming high CPU, even if the overall CPU percentage (shown on the Performance tab) appears moderate. This indicates a few cores might be maxed out.
• On the Performance tab, click the CPU graph to see individual core activity. Look for any cores hitting 100% saturation. 2. Advanced Network Diagnostics (Crucial for Real-Time Apps):
• Teams Call Health: During a Teams meeting, click the "..." (More actions) menu > "Call health." Focus on:
  • Network Tab:
    • Round Trip Time (RTT): Look for consistently high values (>100ms) indicating latency.
    • Packet Loss: Any significant packet loss (even small percentages) severely impacts real-time audio/video.
    • Jitter: High jitter (inconsistent packet arrival) can cause choppiness and delays.
  • Video and Audio Tabs: Check received/sent frames and bitrate for issues.
• Basic Connectivity Tests:
  • Open Command Prompt (cmd) and run ping 8.8.8.8 -t. Watch for high ping times or dropped packets.
  • Try a wired (Ethernet) connection instead of Wi-Fi to rule out wireless instability or interference.
  3. Comprehensive Driver Updates & System Health:
• Lenovo Vantage: Install and run Lenovo Vantage from the Microsoft Store. This tool is excellent for keeping all your ThinkPad's drivers (chipset, audio, network, graphics) and BIOS up to date. Prioritize these updates.
• Manual Driver Check: Visit the official Lenovo support website for your specific P14s model and manually check for the absolute latest versions of all drivers, especially chipset, network, and audio.
• BIOS Update: Ensure your BIOS is on the latest version. 4. Power Management Settings:
• High Performance Mode: During a meeting, set your laptop's power mode to "Best performance" (click the battery icon in the system tray).
• Windows Power Plan: In Control Panel > Hardware and Sound > Power Options, ensure you're on a "Balanced" or "High performance" plan.
• Lenovo Vantage Power: Check if Lenovo Vantage has any aggressive power-saving profiles enabled during calls that might throttle your CPU. 5. Antivirus/Security Software Interference:
• Run a full scan with Windows Defender or your preferred antivirus.
• Consider temporarily disabling your antivirus during a brief test meeting (if safe and allowed by your IT policy) to see if it's the cause.
• Add Microsoft Teams executables (Teams.exe and ms-teams.exe) and its data folders (within %appdata%\Microsoft\Teams) to your antivirus's exclusion list.

6. Feature Disablement (for Testing):

• During a meeting, try turning off your video. Does performance improve?
• Try disabling incoming video from others.
• Avoid using background effects/blur, especially complex ones, as they consume significant CPU resources. 7. Event Viewer Check:
• When a slowdown occurs, immediately check Event Viewer (search for it in Start).
• Go to Windows Logs > Application and System. Look for any critical errors, warnings, or informational events related to system performance, drivers, or Teams itself around the time of the slowdowns.

Please let me know the results of these steps, particularly any findings from Task Manager (individual core usage), Teams Call Health metrics (RTT, packet loss, jitter), or Event Viewer entries. This information will be crucial for further investigation. Please note that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.
