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

If you’re noticing sudden spikes in bandwidth usage, CPU load, or RAM consumption inside CyberPanel, you’re not alone. In 2025, heavy bot traffic, misconfigured caching, and media-heavy websites are the top reasons servers slow down.

High bandwidth usage can:

•  Slow down your websites

• •  Trigger hosting suspensions due to quota limits
• •  Cause “Resource Limit Reached” or 503/508 errors
• •  Increase server costs
  
  At CloudCareHost.com, we troubleshoot this issue for hundreds of clients every month. This updated 2025 guide covers:
  
  •  Why CyberPanel shows high bandwidth
• •  How to diagnose the root cause
  •  Proven fixes to reduce bandwidth and CPU load
  •  Long-term prevention tips based on real hosting cases
  
  This is the most complete and updated CyberPanel optimization guide you’ll find online.
  
  1. What Bandwidth & Resource Usage Mean in CyberPanel
  
  Understanding the metrics helps in fixing the issue logically.
  
  • Bandwidth → This is the total data transferred from your server to users, bots, crawlers, and APIs. Every visit, file request, or download increases bandwidth usage.
• 
  • Resources → CPU + RAM consumption from: PHP processes, MySQL queries, Cron jobs, Scripts, Bots, Heavy plugins
  
  At CloudCareHost.com, our servers track these metrics with real-time monitors to isolate unusual patterns instantly.
  
  2. Most Common Reasons for High Bandwidth Usage in CyberPanel (2025)
  
  Here are the real-world causes we see most frequently:
  
  • 1. Large Media Files (Uncompressed images, videos, backups) – Massive JPG/PNG/MP4 files quickly overload bandwidth.
• • Bot / Spam Traffic (MOST COMMON IN 2025) – AI scrapers + malicious crawlers aggressively hit pages.
• • Missing or Incorrect Caching – If LiteSpeed Cache isn't configured properly, every page loads uncached.
• • Heavy or Stuck Cron Jobs – Background scripts repeatedly running cause CPU and RAM spikes.
• • Malware or Backdoors – Compromised sites send outbound requests, drain bandwidth, or mine crypto.
• • Low Bandwidth Quota – A small plan quota can falsely trigger “high bandwidth usage” alerts.
  
  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. How to Check Bandwidth & Resource Usage in CyberPanel
  
  CyberPanel offers several built-in tools to track what’s using up your bandwidth or CPU.
  
  CyberPanel Dashboard: 
  
  • 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. How to Fix High Bandwidth & High 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.
