How to Fix High Bandwidth and Resource Usage in CyberPanel (2025 Guide)

Fix High Bandwidth and Resource Usage in CyberPanel (2025 Guide)

Introduction: Why CyberPanel Shows High Bandwidth or Resource Usage

Managing websites through CyberPanel is usually smooth, until you suddenly notice your server bandwidth or resource usage spiking. High bandwidth consumption can slow down sites, affect performance, or even lead to temporary suspensions if limits are reached.

At CloudCareHost.com, we frequently assist clients with this exact issue. In this detailed 2025 guide, we’ll explain:

• What causes high bandwidth and resource usage in CyberPanel

• • How to diagnose the problem
• • And step-by-step methods to fix and prevent it permanently
  
  
  1. Understanding Bandwidth and Resource Usage in CyberPanel
  
  Before fixing the issue, it’s important to understand what’s actually happening.
  
  • Bandwidth → the total data transferred between your server and users. Every page view, file download, and media request adds to your bandwidth total.
• 
  • Resources → CPU and RAM usage on your server. High CPU or memory load can slow down websites or trigger “resource limit reached” errors.
  
  At CloudCareHost.com, our optimized hosting environments continuously monitor both parameters to ensure peak performance and stability for every website.
  
  
  2. Common Causes of High Bandwidth Usage
  
  Here are the most common reasons why bandwidth or resource usage spikes in CyberPanel:
  
  • Large Media Files or Downloads – Hosting uncompressed videos, images, or downloadable files.
• • Bot or Spam Traffic – Automated crawlers repeatedly requesting pages.
• • Improper Caching Configuration – A Missing or misconfigured cache makes the server regenerate pages on every visit.
• • Background Cron Jobs or Scripts – Repetitive or stuck scripts silently consume CPU and RAM.
• • Malware or Security Breaches – Hacked sites sending or receiving data without your knowledge.
• • Low Bandwidth Limit Assigned to Domain – A small quota can trigger false “high usage” alerts or downtime.
  
  If you’re hosting with CloudCareHost, you can easily monitor and fix these using CyberPanel’s dashboard, or contact our team for a quick optimization checkup.
  
  
  3. Checking Resource and Bandwidth Usage in CyberPanel
  
  CyberPanel offers several built-in tools to track what’s using up your bandwidth or CPU.
  
  Dashboard Overview: 
  
  • Navigate to: Websites → List Websites → Manage → Website Statistics → Review bandwidth and traffic data per domain.
  
  Command Line Monitoring
  
  • Use commands like: top, htop, iftop
  
  These show active processes and live bandwidth usage in your server terminal.
  
  Access Logs
  
  • Path: /home/domainname/logs
  
  Look for repeated hits from the same IP or unusual traffic patterns.
  
  
  4. Fixing High Bandwidth and Resource Usage in CyberPanel
  
  Once you’ve identified the source, apply these proven fixes.
  
  I) Enable LiteSpeed Cache
  
  CyberPanel includes LiteSpeed Cache, which drastically reduces data transfer by serving cached copies of pages.
  
  Steps:
• 
  • Install the LiteSpeed Cache plugin (for WordPress).
• 
  • Enable caching in the CyberPanel dashboard.
• 
  • Purge and rebuild cache regularly after content updates.
  
  Benefit: Reduces bandwidth by up to 70% and speeds up page load times.
  
  II) Use a CDN (Content Delivery Network)
  
  CDNs offload your static content (like images, JS, and CSS) to global edge servers.
  
  Recommended CDNs:
  
  • Cloudflare
• 
  • Bunny.net
• 
  • StackPath
  
  At CloudCareHost, we integrate CDN setups for clients to reduce bandwidth load and improve performance worldwide.
  
  III) Block Malicious Traffic and Bots
  
  Spam bots can inflate your traffic artificially.
  
  Use one or more of the following methods:
  
  • Add firewall rules in Cloudflare or CSF Firewall
• 
  • Block repeated IPs in .htaccess
• 
  • Enable reCAPTCHA on forms
• 
  • Use fail2ban for brute-force protection
  
  IV) Optimize and Compress Media Files
  
  Large media files can drain bandwidth quickly.
  
  Use plugins like:
• 
  • Imagify
• 
  • ShortPixel
• 
  • Smush
  
  Compress images before uploading and consider serving videos from YouTube or Vimeo instead of self-hosting.
  
  V) Increase or Set Unlimited Bandwidth for Domains
  
  One of the simplest but most overlooked fixes is adjusting your bandwidth limit inside CyberPanel.
  
  Steps:
• 
  • Log in to CyberPanel
• 
  • Go to Websites → List Websites
• 
  • Click Manage beside the domain
• 
  • Click Modify Website
• 
  • Increase the bandwidth quota or choose Unlimited
  
  This prevents unnecessary “high usage” alerts and downtime caused by low quotas.
  
  VI) Keep CMS and Plugins Updated
  
  Outdated CMS cores or plugins (like WordPress, Joomla, or Drupal) can lead to vulnerabilities that consume resources. Always keep everything updated and remove unused plugins or themes.
  
  VII) Review Backup Settings
  
  Frequent local backups can consume disk space and bandwidth, especially if multiple copies are stored.
  
  Pro Tip: Schedule off-site backups to Google Drive, Dropbox, or AWS S3 to save bandwidth.
  
  
  5. Advanced Optimization Tips
  
  If you’re still facing spikes after basic fixes, apply these expert-level optimizations:
  
  • Use CSF Firewall with CyberPanel to limit requests
• 
  • Install fail2ban to stop brute-force attacks
• 
  • Enable HTTP/3 in LiteSpeed for faster data transfer
• 
  • Offload large media to AWS S3 or Google Cloud Storage
• 
  • Enable GZIP Compression for smaller response sizes
  
  At CloudCareHost.com, our servers are pre-optimized with these configurations, helping users maintain consistent performance even during traffic surges.
