After reading this article, your virtual machine will no longer lag like a PPT!
A veteran programmer with 15 years of experience reveals: 90% of virtual machine lag is caused by these pitfalls. Statistics show that 76% of developers have been tormented by virtual machines…
No Need to Panic About Virtual Machine Lag! Quick Troubleshooting in 3 Minutes
1️⃣ Basic Troubleshooting (Easy for Beginners)
Step 1: Check if Virtualization is Enabled – Press Win+R, type msinfo32 – Look for “Virtual Machine Monitor Mode Extensions” in the “System Summary” – If it shows “Yes”, it is enabled; if it shows “No”, you need to enter BIOS settings.
I spent an entire day last year on this issue, only to find out that virtualization was not enabled in the BIOS…
Steps to Enable Virtualization in BIOS: 1. Restart your computer and press F2 or Del to enter BIOS (the key may vary by motherboard) 2. Find Advanced/CPU Configuration 3. Change Intel Virtualization Technology to Enable 4. Save and exit.
2️⃣ Advanced Optimization (Instant Results)
Memory allocation is key to virtual machine performance!
Recommended Configuration: – System memory ≥16G: Allocate 4-8G to the virtual machine – System memory 8G: Suggest allocating 2-3G – CPU: Allocate at least 2 cores.
Recommended Tools: – VMware Workstation Optimizer – VirtualBox Performance Monitor – Process Lasso (CPU priority scheduling).
3️⃣ Professional Tuning (Smooth as a Physical Machine)
Taking VMware as an example, these settings must be changed:
- Disable unnecessary features:
- 3D Acceleration (uses GPU) - Printer Sharing - Drag and Drop-
Optimize Disk Performance: – Pre-allocate all disk space – Place virtual disk files on a solid-state drive – Disable disk compression.
-
Memory Optimization Tips:
- Lock physical memory - Disable page file swapping - Turn off memory ballooning.
