Servers & Hosting (Plesk, CloudPanel, Linux)
CloudPanel Performance Check
Check and tune a CloudPanel server's PHP, Nginx and database settings for your actual traffic.
The Problem
CloudPanel ships with sensible defaults, but default settings rarely match your specific sites — one slow site can be starving the others of PHP-FPM workers or memory.
About this problem
CloudPanel's defaults are sensible for a typical single site, but once multiple sites share a server, one resource-hungry site can quietly starve PHP-FPM workers or memory from the others without any obvious error — it just shows up as everything feeling slower. The cause is rarely visible from the slow site itself; it's visible from the server's resource usage as a whole.
This usually comes up when a server hosting several sites starts feeling inconsistent, fast sometimes and sluggish at others.
What's Included
- Reviewing PHP-FPM pool sizing across sites
- Checking Nginx and database configuration against available resources
- Identifying the specific site(s) causing the most load
- Before/after measurements
What's NOT Included
- Upgrading your VPS plan
- Application code-level optimisation
- CDN or external caching layer setup
How It Works
- Review PHP-FPM pool sizing across every site on the server, not just the one that feels slow.
- Check Nginx and database configuration against what the server's actual RAM/CPU can support.
- Identify which specific site(s) are consuming disproportionate resources.
- Adjust pool limits or site-specific settings to rebalance resource allocation.
- Take before/after measurements under comparable load to confirm the fix actually helped.
In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.
Frequently Asked Questions
- Why do all my sites slow down at the same time on CloudPanel?
- One resource-heavy site can consume shared PHP-FPM workers or memory, starving the others — this looks like a server-wide problem but usually traces back to one specific site.
- How many websites can CloudPanel handle on one server?
- It depends entirely on the server's resources and each site's traffic — there's no fixed limit, but performance degrades once combined demand exceeds what's available.
- Does CloudPanel show server resource usage?
- It shows basic metrics, but identifying which specific site is the actual bottleneck usually needs a closer look than the dashboard provides on its own.
- Will adding more RAM fix slow CloudPanel sites?
- Sometimes, but if PHP-FPM pools aren't configured to use the extra RAM, the upgrade alone won't help — tuning usually needs to happen alongside any resource increase.
- Can one bad plugin slow down other websites on the same server?
- Yes, if that plugin causes excessive database queries or PHP processing, it can consume shared server resources that other sites on the same box also depend on.
- How do I check if my site is the one causing server slowdowns?
- Comparing resource usage (CPU, memory, active PHP-FPM processes) per site during a slow period usually points clearly to the culprit.
