Fix a Slow WordPress Website on ReadySpace WebSpace (Complete Checklist)
Purpose
This guide provides a clear, step-by-step checklist to diagnose and fix a slow WordPress site hosted on ReadySpace WebSpace. Follow each section in order before considering an upgrade.
Who Should Use This Guide
- Website owners and administrators using ReadySpace WebSpace.
- Developers and IT staff managing WordPress performance.
- SMEs who need a practical, actionable optimization workflow.
Prerequisites
- Access to ReadySpace WebSpace control panel (cPanel).
- Access to the WordPress Admin Dashboard.
- Basic familiarity with plugins, caching, and WordPress settings.
Quick Navigation
- Check if LSCache is enabled
- Check if Redis is enabled and connected
- Check WP Toolkit security
- Check WordPress Site Health
- Check if QUIC.cloud CDN is enabled
- Post-deployment checklist
- When to upgrade
- Maintenance & updates
- Security hardening (optional)
- References
1) Check if LSCache is Enabled
Ensure LiteSpeed Cache is installed and actively caching pages.
- In WordPress Admin, go to Plugins → Installed Plugins and confirm LiteSpeed Cache is Active.
- Open LiteSpeed Cache → General and set Enable Cache to ON.
Verify cache headers
From your computer, run a header check. You should see x-litespeed-cache with a value like hit after a second request:
curl -I https://your-domain.com/ | grep -iE "x-litespeed-cache|cache-control"
If the header is missing or shows miss repeatedly, your page may be uncachable (e.g., logged-in users, dynamic query strings, or cache disabled for that path). Review LiteSpeed Cache → Cache and LiteSpeed Cache → Excludes.
2) Check if Redis Is Enabled and Connected
Use Redis for object caching to reduce database load.
- In cPanel, ensure Redis is available and enabled for your WebSpace plan.
- In WordPress, install/activate a Redis object cache plugin (e.g., Redis Object Cache).
- Go to Settings → Redis (or the plugin’s page) and click Enable Object Cache. Status should show Connected.
Verify Redis status in WordPress
WordPress Admin → Settings → Redis → Status: Connected
If Redis cannot connect, check that your WebSpace plan includes Redis and no conflicting object cache plugins are active.
3) Check WP Toolkit Security Is Cleared
Use WP Toolkit in cPanel to fix known security risks that can impact performance.
- In cPanel, open WP Toolkit.
- Select your site → review Security tab and apply all recommended fixes until status is Cleared / no pending issues.
Keeping your site secure prevents malware and rogue scripts that slow down page loads.
4) Check WordPress Site Health
Confirm WordPress reports a healthy configuration.
- In WordPress Admin, go to Tools → Site Health.
- Status should show a smiley face and Good.
- Resolve items listed under Critical issues and Recommended improvements.
WordPress Admin → Tools → Site Health → Status: Good ????
5) Check if QUIC.cloud CDN Is Enabled
QUIC.cloud pairs natively with LiteSpeed to accelerate global delivery.
- In WordPress, open LiteSpeed Cache → General → General Settings and link your domain to QUIC.cloud.
- Enable CDN in LiteSpeed Cache → CDN (or QUIC.cloud section) and complete the DNS/verification steps.
- Purge all caches once activated: LiteSpeed Cache → Toolbox → Purge All.
Verify CDN headers
Look for QUIC.cloud headers such as x-qc-cache and/or x-qc-pop on requests:
curl -I https://your-domain.com/ | grep -iE "x-qc-|x-litespeed-cache|cf-cache-status|server"
Some headers differ by POP or integration mode; the key is that responses are served quickly and cacheable objects return HIT after warm-up.
Post-Deployment Checklist
- Run performance tests:
- Confirm headers show cache usage (x-litespeed-cache: hit, x-qc-cache: HIT after warm-up).
- Verify the site feels fast on both desktop and mobile (render within ~2–3 seconds for key pages).
- Check heavy pages (homepage, product/category, blog posts) and logged-out vs logged-in performance.
When to Upgrade
If you completed all steps above and the site is still slow, move up the stack to get more resources.
| Scenario |
Action |
Why |
| Optimizations done, occasional slowdowns |
Upgrade to the next WebSpace plan |
More CPU/RAM/IO limits for traffic spikes and heavier plugins |
| Consistent slowness, complex plugins, higher traffic |
Upgrade to a Cloud Server with cPanel |
Dedicated resources and finer tuning (PHP workers, Redis memory, MySQL configs) |
Tip: Track performance before and after each change (PageSpeed/GTmetrix). This helps justify upgrades and isolates bottlenecks (theme, plugin, DB, or network).
Maintenance & Updates
- Keep WordPress core, themes, and plugins updated (use WP Toolkit for safe updates).
- Periodically purge LiteSpeed cache after major changes (LiteSpeed Cache → Toolbox → Purge All).
- Monitor object cache hit ratio (Redis plugin dashboard) and increase object cache if needed.
- Use image optimization (LiteSpeed Image Optimization / WebP/AVIF) and lazy load.
- On Premium WebSpace plans, use Site Quality Monitoring in cPanel to watch performance over time.
Security Hardening (Optional)
Security issues often lead to performance issues. Apply these baseline protections:
- Restrict access at the server firewall to only ports 80, 443, and 22.
- Enable fail2ban (if available on your plan) to block brute-force attempts.
- Disable password SSH logins; use SSH key authentication.
- Harden WordPress logins (reCAPTCHA, limited login attempts, strong passwords).
Common Pitfalls to Avoid
- Multiple caching plugins active at once (conflicts). Use LiteSpeed Cache only with QUIC.cloud.
- Unoptimized media (huge images/videos) and heavy page builders with unused blocks.
- Bloated plugins (disable features you don’t use; remove unused plugins/themes).
- Chat widgets and third-party scripts loaded on every page (defer or load conditionally).
