My Site Is Slow or Hitting Resource Limits

What's happening

Your website is loading slowly or returning errors because it's using too much CPU, memory, or disk.

How to diagnose

1. Check resource graphs: Go to your website dashboard and review the CPU, memory, and I/O graphs. Look for spikes or sustained high usage.

2. Check the error log: Go to Developer Tools → PHP → php-error.log. Memory exhaustion or timeout errors point to specific scripts.

3. Check disk usage: If your disk is full, uploads, database writes, and even email will stop working.

How to fix it

Quick wins

• Enable caching: Turn on opcode caching and Redis. If you're on LiteSpeed, install the LSCache plugin. See Caching options.
• Optimize images: Large, uncompressed images are a common cause of slow pages.
• Deactivate unused plugins: Every active plugin consumes resources.
• Update PHP: Newer PHP versions are significantly faster. See Choosing your PHP version.

If you're hitting hard limits

• Increase memory_limit in php.ini if you're getting memory errors.
• If you've optimized everything and still need more resources, contact representative@trustedge.gt about upgrading your plan.
