This article outlines common causes of slow workstation performance and provides corrective actions. Use this guide when experiencing lag, slow toolpath calculations, delayed STL loading, or general system instability.
1. Insufficient RAM
Symptoms
Freezing during scanning or design / CAM calculations
Slow STL imports / processing times
Delays when switching applications
Likely Cause
RAM usage reaches maximum capacity, forcing the system to rely on disk swapping.
Solution
Confirm RAM usage in Task Manager.
Upgrade RAM if usage regularly exceeds 60-80%.
IMPORTANT: RAM limitations affect CAD more severely than CAM.
2. Storage Near Capacity
Symptoms
Slow scan import / processing times
Delayed or failed save operations
Long application launch times / general slowness to Windows / PC Environment
Cause
Storage drives decrease in performance significantly when they are nearly full.
Solution
Maintain at least 15–20% free disk space.
Archive old cases to external locations or setup File Maintenance to automatically free up space.
3. CPU Thermal Throttling
Symptoms
MillBox calculations progressively slow
System becomes sluggish during heavy tasks
Fans running at maximum speed
Cause
CPU temperature reaches threshold and reduces frequency.
Solution
Inspect airflow paths.
Clean dust from the front grate and intakes.
Verify liquid cooling system fans operate normally.
TIP: High ambient lab temperatures may also reduce CPU stability.
4. Excessive Background Applications
Symptoms
Lag during mesh editing
Slow viewport interaction
Stuttering during heavy computation
Cause
Unnecessary programs consuming CPU or memory.
Solution
Close all nonessential applications, especially web browsers and cloud sync software.
5. Outdated GPU or System Drivers
Symptoms
Viewport lag in CAD
Flickering models
Slow rendering
Cause
Driver versions incompatible with CAD rendering engines. / Faulty Hardware
Solution
Update GPU drivers to the recommended version for your CAD software. / Replace GPU
6. Network or File Transfer Issues
Symptoms
Slow project loading
Delayed access to shared folders
Cause
Network bandwidth limitations or unstable WiFi.
Solution
Use wired Ethernet whenever possible.
Summary
Workstation slowdowns typically originate from memory limitations, storage capacity issues, thermal restrictions, or background processes. Following the steps above resolves most performance issues. For persistent problems, contact Level Up Support for diagnostic assistance.
