A website that feels fast starts long before the first image appears. The web server has to accept a request, run PHP, retrieve information from the database, assemble a page and send it efficiently. When every step adds delay, front-end optimisation alone cannot repair the foundation. That is why Gigatech uses LiteSpeed Enterprise and builds a complete caching and security layer around it.
LiteSpeed is not a magic speed button, nor does it replace a well-built website. It is a powerful foundation because the web server, the LiteSpeed Cache plugin for WordPress, Redis object caching, HTTP/3 and server-level protection can work directly together. As a result, fewer requests need to travel through the complete WordPress and database stack.
TTFB: where speed begins
Time to First Byte is the time between a browser request and the first response from the server. It is not the same as total load time, but a high TTFB delays everything that follows. The browser cannot continue rendering until the server starts responding.
A dynamic WordPress page may run PHP and execute many database queries on every visit. With a valid full-page cache, LiteSpeed can serve a previously generated result directly. The route becomes much shorter: request, cache check, response. This reduces processing, database load and waiting time. Under traffic spikes the difference becomes even more important because cached pages use far less server capacity.
The browser requests a page.
LiteSpeed checks for a current cached copy.
A cache hit avoids PHP and much database work.
The browser can start rendering earlier.
LSCache works close to the web server
There are many WordPress caching plugins. The key distinction of LiteSpeed Cache is its communication with the cache engine inside LiteSpeed Web Server. The plugin understands WordPress: it can purge a page after an update, manage separate variations for logged-in users and exclude sections that must remain dynamic. The server can then deliver the stored page without fully booting WordPress.
This matters for shops and content-heavy websites. A cart, account page or current stock level must never be served as one general copy to every visitor. Caching therefore requires careful configuration. We prefer correct and predictable behaviour over an aggressive setting that looks fast in a test but breaks real functionality.
Redis: a different layer for a different problem
Full-page caching and object caching are often confused. A page cache stores a complete response. Redis can keep frequently used WordPress objects and results in fast memory. When a request cannot be served from the page cache, WordPress may avoid recalculating or retrieving the same information from the database.
Redis cannot fix a poor database model by itself. It is most useful for repeated read work such as settings, menus and frequently used query results. We therefore support Redis on plans where the workload can benefit. The combination is logical: LiteSpeed prevents as many full WordPress runs as possible, while Redis accelerates the work that remains.
HTTP/3 and modern connections
LiteSpeed supports HTTP/3 over QUIC. With older TCP connections, the loss of one packet may temporarily hold back other data streams. QUIC keeps streams more independent and handles changing mobile networks more efficiently. This does not make every page twice as fast, but it can remove avoidable delay and make transfers more resilient, especially on mobile or unstable connections.
Stopping bad bots before they exhaust WordPress
A significant share of internet traffic is not human. Bots test credentials, request large numbers of URLs and target common WordPress endpoints such as wp-login.php and xmlrpc.php. Even unsuccessful attacks can consume CPU, PHP workers and database capacity.
LiteSpeed Enterprise includes WordPress brute-force protection and can throttle, deny or challenge hostile traffic. At Gigatech this is one layer in a larger design. Imunify360 adds firewall rules, reputation data, malware detection, Proactive Defense and anti-bot measures. CloudLinux limits the resources one hosting account can consume. The goal is both to stop attacks and to prevent hostile traffic aimed at one website from affecting the rest of the platform.
Why hardware still matters
Software can remove waiting, but it cannot turn slow storage, insufficient memory or an overcrowded server into premium infrastructure. Fast CPU cores help PHP, sufficient RAM supports caches and processes, and fast SSD storage reduces database and filesystem delays. We combine LiteSpeed with enterprise hardware, controlled account limits and active monitoring. Caching multiplies the value of good infrastructure; it is not an excuse to cut corners.
What you can do
- Use one properly configured caching solution and avoid overlapping plugins.
- Optimise large images and lazy-load non-critical media.
- Limit heavy plugins and investigate slow database queries.
- Test changes both as a visitor and as a logged-in administrator.
- Measure TTFB and Core Web Vitals across several pages and times.
