Hosting Glossary
What is TTFB?
What TTFB actually means, minus the jargon — with the example that makes it obvious.
The short answer
TTFB measures the delay between requesting a page and receiving its first byte — the server-and-network share of perceived speed.
Below: the fuller explanation, an analogy that makes it stick, why it matters in practice, and where you'll actually meet it.

Humans if you're stuck
It bundles DNS, connection setup, TLS and the server's thinking time — everything before page weight enters the story. High TTFB points at hosting, caching or backend drag; low TTFB with slow pages points at the pages.
Cache-hits collapse it: a served-from-cache page's TTFB is network distance plus microseconds, which is why caching status dominates the metric.
TTFB (Time To First Byte), by analogy
The kitchen's time-to-first-dish — how long after ordering before anything reaches the table; portion size (page weight) delays the rest of the meal separately.
Hold onto that picture and most of the documentation you'll ever read about it becomes considerably less mysterious.
The practical stakes
TTFB is the diagnostic that splits every speed problem in two — hosting-side or page-side — and the floor under Core Web Vitals; you cannot LCP faster than your first byte arrives.
You don't need to operate this layer daily — you need to recognise it when it's the explanation for something, which is exactly when this page pays for itself.
What it looks like in practice
A site tests at 900ms TTFB uncached and 80ms from cache — the diagnosis writes itself: extend cache coverage, and investigate what the uncached path is computing.
Ordinary, once seen — which is the point: most hosting concepts are simple machinery wearing intimidating names.
Where you'll meet it on our platform
On our hosting this mostly takes care of itself — the platform applies the sensible defaults, and the panel exposes the controls when you want them. The concepts worth knowing next: Cache, Core Web Vitals, NVMe and LiteSpeed.
Business email on your own domain is included, not sold back as an add-on.
Why we wrote a hundred definitions
We think unexplained jargon is a service failure — this glossary is the support desk's accumulated translations, published where the search engines can hand them out.
Every plan includes free SSL that renews itself, so the padlock is never your job.

Why HostingAlly
Every plan includes this, whatever you pay
Honest about what you can skip
Most terms are recognise-level, not operate-level — the glossary says which is which.
The next reads, mapped
This entry connects to Cache and Core Web Vitals — concepts travel in packs, and the pack is linked.
The practical stakes named
Not just what it is — when it's the answer to a problem you're having.
Plain English first
Every term defined for site owners, not for other sysadmins — jargon translated, not restated.
One term, fully landed
TTFB defined, pictured by analogy and placed in your own control panel — recognise-level in a single read.
Grounded in a real platform
Examples reference the hosting you'd actually use, not abstract diagrams.
Getting Started
How to get going
- 1
Spot it in your own setup
Open your control panel and find where this concept lives — seeing it attached to your own site is what converts definition into understanding.
- 2
Check the defaults
Our platform ships sane defaults for this — verify rather than assume, and you'll know your setup instead of hoping about it.

FAQ
Your questions, answered
What's a good TTFB number?
Cached pages to nearby visitors: under ~200ms comfortably. Uncached dynamic pages: 200-500ms on healthy hosting. Sustained near a second signals something diagnosable — caching gaps, plugin drag, or hosting mismatch.
How do I improve TTFB?
In order of leverage: page caching (skips computation), PHP 8.x and OPcache (faster computation), Redis and NVMe (faster data), then pruning slow plugins and external calls. Page-weight optimisation, note, is not on this list.
Where is your company based?
HostingAlly is a trading name of Fairdeal Renovations Limited, a company registered in England and Wales — a real, verifiable business with published terms under English law, which is worth checking about any host before you hand them your domain.
How long does it take to get started?
Minutes — hosting activates on payment, the domain (free for year one on annual plans) connects immediately, and one-click installers put WordPress or 400+ other apps live the same sitting. If you have an existing site, our team migrates it free, usually within 24 hours.
What does your 24/7 support actually cover?
Real people at every hour, and a scope that includes the practical questions — email setup, DNS, WordPress issues, restores — not just 'the server is up, ticket closed'. Pre-sales questions are welcome too; ask us something difficult and judge the reply.
Do you include email with hosting?
Yes — mailboxes on your own domain come with every hosting plan, with webmail, IMAP/POP/SMTP access and spam filtering. Standalone email hosting also exists for domains whose websites live elsewhere.
Where are your servers located?
Our hosting infrastructure runs from European datacentres with London at the core, behind server-level caching that keeps cached pages fast worldwide. For most sites, platform quality — NVMe storage, LiteSpeed, sensible server density — matters far more than the datacentre's postcode.
Keep exploring
Cache
A cache stores the results of expensive work for instant reuse.
LiteSpeed
LiteSpeed is a high-performance web server with Apache compatibility and built-in caching — the engine behind our hosting's speed.
Joomla Hosting
Joomla-ready hosting with one-click install and free migration in.
VPS Hosting
KVM virtual servers with root access, DDoS protection and flat pricing.
Planning to switch hosts? Grab the checklist here.
The steps that keep a site migration dull rather than dramatic: what to back up first, how to shift email across without losing a single message, when to touch DNS, and the two mistakes behind nearly every hour of downtime we come across.
Your site deserves better hosting.
Fast NVMe hosting, free SSL and migration, and real people on support around the clock — at prices that stay put.
