Site speed is built in, not added on. The default stack on every Flashcloud hosting plan delivers fast pages without you installing plugins, configuring caches, or signing up for a CDN.
Two layers of speed: the server and the edge.
Server: LiteSpeed + LSCache
We don't run nginx + PHP-FPM. We run LiteSpeed Web Server with LSCache built in.
- LiteSpeed handles requests faster than nginx for the typical web hosting workload. Particularly noticeable for WordPress, where LiteSpeed's native PHP integration cuts request overhead by 30–50%.
- LSCache is a full-page cache at the server level — when a page is cached, the request never touches PHP. It's served from memory in milliseconds.
- Smart invalidation — LSCache talks to WordPress (and other CMSes via plugins), so when you update a page or publish a post, only the affected pages are evicted. The rest stay hot.
For shared and WordPress hosting, this is on by default. You don't configure anything.
WordPress-specific cache stack
Beyond LSCache, every WordPress install gets:
- LiteSpeed Cache plugin — pre-installed and pre-configured, the bridge between WordPress and the server-level LSCache. Adds page caching, image optimization, CSS/JS minification, critical CSS generation, browser cache headers.
- Redis object cache — Redis runs on every WordPress hosting account, wired into your install. Memorizes database query results so subsequent requests skip repeated lookups.
You don't install W3 Total Cache, WP Rocket, Object Cache Pro, or anything similar. It's already there.
For full details, see The cache stack we ship with every WordPress install.
Edge: Cloudflare
On top of the server stack, Cloudflare sits at the edge:
- Anycast routing — DNS queries and (with proxy mode) HTTP requests hit the nearest Cloudflare datacenter, not your origin server in one location.
- DDoS scrubbing — automatic, invisible.
- HTTP/3 and Brotli — modern protocols and compression for fast delivery.
- Static asset caching — when a visitor in Australia loads your site hosted in NJ, Cloudflare in Sydney serves the images and CSS, only the dynamic HTML touches your server.
- Optional proxy mode — flip the orange cloud on a record to put Cloudflare in front of your site fully. Adds full-page caching at the edge, WAF protection, image optimization at the CDN level.

Hardware
Underneath all the software, the hardware matters:
- NVMe SSD storage — random reads (database queries, WordPress page renders) hit disk in microseconds rather than milliseconds.
- Modern CPUs — single-core performance matters more than core count for typical PHP workloads. We pick fast cores.
- ECC RAM — catches single-bit memory errors that would silently corrupt data on consumer hardware.
- Fat network pipes — every server has redundant uplinks so you don't share a 1Gbit pipe with a thousand other accounts.
What this means for your site
For a typical WordPress site on Flashcloud, with the default stack:
- Time to first byte (TTFB): 100–200ms for cached pages, 300–600ms for uncached.
- Full page load: 1–2s for cached, 2–3s for uncached, depending on theme and plugins.
- Lighthouse Performance score: 80–100 on cached pages out of the box.
These are typical for sites that haven't been heavily optimized — the stack does the work.
When to do more
The default stack handles 95% of cases. Worth tuning further if:
- You're running a high-traffic WooCommerce store with lots of dynamic checkout pages.
- You have a custom theme or plugin generating heavy queries.
- You're optimizing for a specific Lighthouse score above 95.
- You're running an application that benefits from edge compute (Cloudflare Workers, etc.).
For a/b/c, the LiteSpeed Cache plugin's tuning options will get you most of the way. For (d), open a ticket — Cloudflare Workers integration is something we can help set up.
What you don't need to install
- Any caching plugin (LSCache plugin is already installed).
- Any object cache plugin (Redis is already wired up).
- A CDN account separate from us (Cloudflare is integrated).
- An image optimization plugin (LSCache plugin handles it).
- A minification plugin (LSCache plugin handles it).
- A "performance pack" of any kind sold by a marketer.
If you read a tutorial that tells you to install one of those, you're working from outdated assumptions about how your hosting works.
