System Resource Monitor

Monitor RAM and CPU usage for all your Roblox instances across devices. Essential for finding the right optimization settings and identifying performance bottlenecks.

What It Shows

RAM usage per Roblox instance - See exactly how much memory each game uses
CPU usage per instance - Monitor processor load for each Roblox app
System totals - Overall device performance and available resources
Real-time monitoring - Continuous updates to track changes

How to Use

Step 1: Start Monitoring

Open Zerx and select “System Resource Monitor”
Choose monitoring mode:
- Single Scan - Check resources once
- Continuous Monitoring - Updates every 10 seconds

Step 2: View Resource Data

The monitor displays detailed information for each device:

resource-display

Device Information:

System RAM usage - Total used vs available memory
CPU usage - Overall system processor load
CPU cores - Number of processing cores available

Per-Instance Details:

Instance name - client, clone1, clone2, etc.
RAM usage - Memory used by each Roblox app
CPU percentage - Processor usage per instance
Process ID - For advanced troubleshooting

Color Coding:

🟢 Green - Good performance (low usage)
🟡 Yellow - Moderate usage (keep an eye on it)
🔴 Red - High usage (may need optimization)

Using the Data

For Optimization Settings

Identifying Problems

Warning Signs:

RAM usage over 1500MB per Roblox instance - Potential memory leaks
CPU constantly above 50% - Overloaded system
System RAM above 90% - Need more memory or fewer instances

Common Issues:

One instance using much more resources - May be stuck or problematic
Gradual increase over time - Memory leaks requiring restart
Sudden spikes - Game loading or intensive activities

Optimization Workflow

1. Baseline Measurement

Run single scan with current settings
Note resource usage per instance
Check for any red/yellow warnings

2. Adjust Settings

Use Device Optimization to modify settings
Increase RAM if instances are using high memory
Adjust CPU cores based on processor usage

3. Test Changes

Run continuous monitoring for 10-15 minutes
Watch for improvements in resource usage
Verify stability hasn’t decreased

4. Fine-tune

Make small adjustments based on data
Test different games - some use more resources
Find optimal balance between performance and quantity

Need Help?

If you see concerning resource usage:

Try reducing the number of instances per device
Use lower graphics settings in games
Consider upgrading system RAM if consistently high
