2. Close unnecessary background apps
3. Disable startup programs you don’t need
4. Use the “Performance” power plan during calls
Activity Monitor (Mac):
1. Monitor CPU usage during calls
2. Quit resource-heavy applications
3. Use “Energy Saver” preferences wisely
4. Check for runaway processes
Memory Management
RAM Usage Patterns:
- Zoom desktop app: 200-500MB base usage
- Each video participant: +50-100MB
- Screen sharing: +100-200MB
- Virtual backgrounds: +200-300MB
Memory Optimization:
# Linux: Clear system cache
sudo sysctl vm.drop_caches=3
# Windows: Use built-in memory cleaner
# Task Manager → Performance → Memory → Clear
# Mac: Purge memory cache
sudo purge
Graphics Acceleration
Hardware Acceleration Settings:
- Enable GPU acceleration in Zoom settings
- Update graphics drivers regularly
- Use a dedicated GPU for video processing
- Disable GPU acceleration if experiencing issues
Virtual Background Performance:
- Requires a modern CPU or a dedicated GPU

Troubleshooting Common Performance Issues
Video Quality Problems
Choppy/Laggy Video:
Cause: Insufficient bandwidth or CPU
Solution:
– Lower video quality in settings
– Close other applications
– Use Ethernet instead of Wi-Fi
– Upgrade internet plan
Poor Audio Quality:
Cause: Network issues or hardware problems
Solution:
– Check microphone settings
– Use a wired headset instead of the built-in mic
– Test different audio devices
– Restart the audio driver
High CPU Usage:
Cause: Multiple video streams or background apps
Solution:
– Turn off the video when not needed
– Use gallery view sparingly
– Close unnecessary applications
– Lower video resolution
Network-Related Issues
Connection Drops:
Diagnosis: Check network stability
Commands:
ping -t 8.8.8.8 # Windows
ping 8.8.8.8 # Mac/Linux
tracert zoom.us # Windows
traceroute zoom.us # Mac/Linux
Bandwidth Testing:
# Test your connection speed
speedtest-cli
# Or use web-based tools
# fast.com (by Netflix)
# speedtest.net (by Ookla)
Enterprise and Developer Considerations
IT Deployment Requirements
System Images:
- Include Zoom in base system images
- Pre-configure security settings
- Set up automatic updates
- Configure firewall rules
Monitoring and Management:
# PowerShell script to check Zoom installation
Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like “*Zoom*”}
# Check Zoom process and resource usage
Get-Process -Name “Zoom” | Select-Object CPU, WorkingSet, VirtualMemorySize
Development Environment Considerations
Virtual Machines:
- Allocate extra RAM (12GB+ recommended)
- Enable hardware acceleration passthrough
- Use paravirtualized network drivers

Conclusion
Meeting Zoom’s system requirements isn’t just about checking boxes – it’s about creating an environment where your video calls enhance productivity rather than hinder it. While you can get by with minimum specifications, investing in recommended hardware pays dividends in reliability, quality, and user experience.
The key is understanding your specific use case and scaling your setup accordingly. A developer doing occasional team calls needs different specs than a sales exec doing client presentations all day. Start with the basics, monitor your performance, and upgrade strategically based on your actual usage patterns.
Remember, the best video call setup is one that works consistently without you having to think about it. When your technology just works, you can focus on what really matters – the conversation.
