WordPress is slow on GARMTECH hosting: performance checklist

A slow WordPress website is usually caused by a combination of caching settings, heavy plugins, unoptimized images, and limited PHP/database resources.

GARMTECH hosting uses LiteSpeed Enterprise, which can significantly speed up WordPress when the LiteSpeed Cache (LSCache) plugin is configured correctly.

Step 0 — Confirm the problem

• Test your site in an incognito/private window (to avoid cached sessions).
• Test from at least two networks (for example, mobile data and Wi‑Fi).
• Check if the problem affects only the admin area (/wp-admin) or the public site.

Step 1 — Enable page caching with LSCache (recommended)

1. In WordPress, install and activate LiteSpeed Cache.
2. Open LiteSpeed Cache → Cache and ensure caching is enabled.
3. Purge cache after changes (Purge All).

If you already use another caching plugin, avoid running two page caches at the same time — it often makes the site slower or unstable.

Step 2 — Check PHP version and mode in Plesk

Modern WordPress versions perform best on recent PHP versions. In Plesk:

1. Open the domain → PHP Settings.
2. Select a newer supported PHP version (if your site and plugins support it).
3. Enable PHP-FPM if available.

Step 3 — Identify slow plugins and themes

• Temporarily disable heavy plugins one by one (especially page builders, security suites, and statistics plugins).
• Check if performance improves on a default theme (for example, Twenty Twenty‑Four).

If you cannot access wp-admin, you can disable a plugin by renaming its folder in wp-content/plugins using Plesk File Manager.

Step 4 — Optimize images and static assets

• Compress large images and use modern formats (WebP if possible).
• Enable browser cache and minification in LSCache (test carefully).
• Remove unused fonts and third‑party scripts if possible.

Step 5 — Database and cron

• Clean up post revisions and transient options (many caching plugins can do this).
• Make sure WordPress scheduled tasks (WP‑Cron) are working properly. If WP‑Cron is disabled, set a real cron job in Plesk.

Step 6 — Check resource usage

If the site is slow only during peak traffic, it can be caused by hitting resource limits. Typical signs:

• Intermittent 503/508 errors,
• Slow admin actions,
• Long page generation times even without large images.

In this case, consider:

• Upgrading the hosting plan, or
• Moving heavy workloads (analytics, background jobs) to external services.

Step 7 — If you use Cloudflare (optional)

• Make sure Cloudflare is not caching dynamic pages like /wp-admin.
• Use “DNS only” for mail-related records (MX, mail hostnames).
• Use “Full (strict)” SSL when your origin has a valid certificate.

Good baseline checklist

• WordPress core + plugins updated.
• LSCache enabled (single page cache only).
• PHP version updated (compatible).
• Images optimized.
• Database cleaned occasionally.
