Why TTFB matters for a PrestaShop store
TTFB (Time To First Byte) measures the time between the browser requesting a page and receiving the first byte of the server's response. Until that first byte arrives, the browser cannot display anything, so TTFB adds to every other loading time.
A PrestaShop store builds its pages dynamically (PHP and database): product pages, categories, the basket and the checkout all call on the server at every visit. A slow server delays every page, whereas a short TTFB leaves more headroom to achieve good Core Web Vitals, in particular LCP (Largest Contentful Paint), which Google uses to assess the loading experience. Google recommends a TTFB of 0.8 seconds or less (web.dev).
HaiSoft PrestaShop hosting targets a TTFB under 80 ms on every plan. To find out more about how this offer was designed, read our article New PrestaShop plan: a predictable, ultra-fast TTFB.
How we measure a TTFB under 80 ms
The TTFB under 80 ms is measured in the browser, using the Chrome or Firefox developer tools (Network tab), on the home page and on every page of the store, with caching enabled.
The value used is the server response time: it does not include the distance between the server and the browser, which depends on each visitor's connection. You can check it yourself: open the developer tools (F12 key), go to the Network tab, reload the page and look at the timing of the main request. The value shown also includes the network round trip specific to your connection.
What PrestaShop managed services include
All HaiSoft PrestaShop hosting plans are fully managed. They include:
- 24/7/365 monitoring of the server and the store;
- daily backups, kept for 7 days (Business) up to 6 months (Business Prestige);
- an included web application firewall (WAF);
- a 99.9% SLA and a 4-hour guaranteed restoration time;
- unlimited support by e-mail and phone;
- free migration of your store.
Technical and security updates for the server and PrestaShop are included in the managed service. Updates to the store's content are not included: they can be carried out by the web agency that built the store or by your webmaster.
The Business Premium and Business Prestige plans run on a dedicated server (a 16 vCPU VM with 16 GB of RAM, or a DS server with 16 vCPU and 32 GB of RAM split into 2 VMs), with SSH access, a dedicated IP and the Hestia panel.

Which plan to choose for your order volume
HaiSoft PrestaShop hosting plans are sized according to the number of orders placed on the store each day:
| Indicative volume | Recommended plan | Server | Price |
|---|
| Around 5 orders per day | Business | Shared server, 50 GB | €49 excl. VAT/month, 1-month commitment |
|---|
| Around 10 orders per day | Business Plus | Shared server, 200 GB, 1 development site | €99 excl. VAT/month, 1-month commitment |
|---|
| Around 20 orders per day | Business Premium | Dedicated server, VM with 16 vCPU / 16 GB RAM, 500 GB | €229 excl. VAT/month, 12-month commitment |
|---|
| Around 100 orders per day | Business Prestige | Dedicated DS server, 16 vCPU / 32 GB RAM, 1 TB, 2 production stores | €649 excl. VAT/month, 12-month commitment |
|---|
Beyond 100 orders per day, or to host several stores and applications, a tailor-made managed dedicated server is a better fit. For a brochure site or a blog, see our managed WordPress hosting.
Migrating your store to HaiSoft
Migration of your PrestaShop store is free on every plan. It is carried out by our technicians and scheduled with you, and is usually seamless for your customers: the store stays available, or is unavailable for just a few minutes. It takes place in 7 steps:
- Audit of your current setup: we check versions (PHP, CMS, plugins or modules), data volumes and the requirements of the new hosting, and verify access (current host, registrar, databases, FTP/SSH).
- DNS preparation: TTLs are lowered in advance to speed up propagation, zones are prepared and the method is chosen (changing name servers or updating A/AAAA records).
- Copy and acceptance testing: files, media and databases are copied to the new environment; if the switchover is scheduled for later, a preview lets you validate the site before it goes live.
- Scheduling: we agree the switchover slot with your teams and, where needed (online shop, frequently updated site), put the original site into maintenance mode to freeze orders, accounts and content.
- Switchover: a final sync of the latest data (orders, changes), then the DNS records are pointed to the HaiSoft infrastructure.
- Reopening and testing: the site reopens as soon as DNS propagation is effective, followed by immediate tests of the checkout, forms, SSL certificates and key user journeys.
- Sign-off and rollback plan: you approve the migration; a full backup of the original site is kept and, in the event of a critical issue, DNS can be pointed straight back to the old server.
For an online store, any interruption is limited to a short maintenance window scheduled with you:
| Type of site | Estimated downtime | Why |
|---|
| Brochure site (WordPress) | 0 minutes | As visitors do not continuously generate data, the original site stays online throughout the DNS switchover. |
|---|
| Online shop (PrestaShop, WooCommerce) | Usually a few minutes, 1 hour maximum | A short scheduled maintenance window freezes the data so that no order or customer account is lost between the final copy and the DNS switchover. |
