Parallels Desktop VM Performance Drops When Testing a Real-Estate Website Project

Hi everyone,

I'm currently testing a real-estate website project called ACE Hive inside a Windows 11 virtual machine on Parallels Desktop for Mac. Everything runs fine initially, but after some time the browser (Chrome and Edge both) starts lagging, especially when running multiple WordPress tools and frontend scripts.

Here are the issues I'm noticing:

• Page preview in WordPress takes unusually long to load
  
  
• Browser freezes for a few seconds during heavy UI interactions
  
  
• Switching between tabs feels delayed
  
  
• Parallels sometimes spikes the CPU even though the workload is light
  

I've already tried:

• Increasing RAM and CPU allocation
  
  
• Switching between Coherence and Full Screen
  
  
• Turning off background processes
  
  
• Testing with a clean VM snapshot
  

Has anyone here faced similar performance drops when working with web-development tasks inside Parallels?
Any recommended settings that improve frontend/browser-heavy workflows?

Thanks in advance!
