Website performance directly affects user behavior, search engine rankings, and overall brand perception. When pages start loading slowly, site owners often look for the problem in design, code, or hosting. In practice, however, a frequent cause of recurring delays is incorrectly configured caching. This is not about the absence of a cache, but about an inappropriate cache size that does not take the actual load on the website into account.
Launching a website on a new VPS is more than just uploading files. It’s a full process that includes configuring the server, connecting a domain, installing a security certificate, checking the website’s functionality, and optimizing its speed. If each stage is completed carefully, the website will run stably, quickly, and without issues — even under heavy load.

Users expect instant responses: if a page takes longer than 2–3 seconds to load, the bounce rate increases sharply. A slow site lowers conversions, worsens SEO, and undermines brand trust. The good news — most problems are predictable and fixable. Below are the five main reasons for slow performance and clear steps to fix them on VPS.
