Magento Speed Optimisation in Derry
Speeding up Magento stores for Derry retailers, where the question is what is preventing the cache from working. Full page caching makes Magento fast, and a single badly built extension marking pages as uncacheable removes that entirely — so the store runs the full application on every request while appearing correctly configured.
Why this comes up
The problem
Full page cache is enabled and hit rates are near zero because something is marking pages private.
What you get
What we deliver
- Cache hit rates measured, since a configured cache is not necessarily a working one
- Extensions identified that mark pages uncacheable or invalidate too broadly
- Private content handled through the intended mechanism rather than by disabling cache
- Varnish configured correctly, as this is where the platform expects to be fast
- Indexers set to update on schedule rather than on save
- Database and Elasticsearch tuned for the catalogue's actual size

Magento Speed Optimisation in Derry — common questions
- Why is the cache not working?
- Usually because something opted out of it. Extensions that inject customer-specific content can mark whole pages private rather than using the mechanism designed for that, so the cache is enabled, correctly configured and serving almost nothing.
- How is that diagnosed?
- By measuring hit rates and then finding the responsible module. The measurement is straightforward and the attribution takes longer, but it is the single most valuable piece of performance work available on most Magento stores.
- Should indexers update on save?
- Almost never on a live store. Updating on save means every catalogue change triggers reindexing immediately, which is why bulk price updates can bring a store to a halt — scheduled updates batch that work and keep the site responsive.
- Is faster hosting the answer?
- Rarely on its own. A store with a broken cache runs the full application for every visitor, and more hardware makes that cheaper to survive rather than fixing it — so establishing why the cache is not being used comes first, and often removes the need entirely.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
