noted the site isn’t hacked but is noticeably slower. and correctly pointed to malware checks and basic performance testing; below is a compact, practical troubleshooting approach that fills gaps those replies left open (server-side causes, backend profiling, and quick mitigations).

A practical diagnostic order:

  • Reproduce the slowdown from several locations and times and capture a network waterfall / HAR so individual requests and TTFB are visible.
  • Run an independent performance report (for example, GTmetrix) and a malware/site-safety scan (for example, Sucuri SiteCheck) to get baseline metrics and alerts.
  • Inspect server-side metrics: CPU, RAM, disk I/O, load average, open connections, and available disk space. Check webserver and PHP-FPM worker counts, swap usage, and recent spikes in processes.
  • Review logs: webserver access/error logs, application logs, and the database slow query log. Look for long-running queries, frequent 5xx errors, large asset requests, or backup/cron jobs running during slow periods.
  • Audit third-party calls and plugins/modules: external analytics/ads, widgets, or updated plugins/themes are common regressions.

Quick fixes to try before deep changes:

  • Enable opcode caching and full-page or object caching; purge and re-test.
  • Serve compressed assets (gzip/brotli), enable proper cache headers, optimize and resize images (modern formats), and defer noncritical JS.
  • Consider a CDN for static assets and verify HTTP/2 or newer transport is enabled.
  • If on shared hosting, request host-side I/O and throttling stats—“noisy neighbor” I/O limits often explain sudden slowdowns.

Collect a short diagnostics pack for further help: HAR file, GTmetrix (or similar) report, server-monitor graphs (CPU/memory/I/O) around the incident time, recent code/plugin changes, and relevant log excerpts. Always take a full backup and test changes in staging when possible.

(This post should not be in the Internet Marketing forum, but I am willing to offer some advice.)

Is it your own website? Do you think it has been hacked? Google's diagnostics tool might turn up some problems, but it might miss others. If it really has been hacked, you might need more thorough measures to detect it and fix the problem.

In the following URL, replace example.com with the domain of the site you want to test:
www.google.com/safebrowsing/diagnostic?site=example.com

This test is pretty good. There are other, free, online test sites you could try too, if you want more than one opinion.

You can easily take a look at the specific items and how long they are taking to download by using your browser's developer's tools. for example, Chrome has the ability as well as IE v9 (hit F12), and even Firefox.

Additionally, for a more thorough "scan" you can use this online web performance test:
