Performance Engineering

Speed is a feature your customers feel

Every extra second between tap and content costs attention, conversion and search visibility. Performance on Salesforce Commerce Cloud is rarely one big problem — it is dozens of small decisions across templates, caching, scripts, images, integrations and jobs. We find the ones that matter, fix them, and make sure they stay fixed.

This website is built the same way: no frameworks, self-hosted fonts, a single compressed stylesheet, modern image formats with explicit dimensions, and third-party scripts deferred until the page is ready. The live panel on our homepage measures it in your own browser.

What we tune

Storefront & Core Web Vitals

• Largest Contentful Paint — critical rendering path, hero imagery, font loading and server response time
• Interaction to Next Paint — long tasks, heavy event handlers, hydration cost and third-party script contention
• Cumulative Layout Shift — reserved space for images, banners, consent tools and late-loading content slots
• Images — Dynamic Imaging Service parameters, modern formats, responsive sizes and lazy loading below the fold
• Third parties — tag inventory, consent-gated loading and a budget every script has to earn

Platform & server

• Page caching — cache-friendly templates, with remote includes isolating personalised slots so the rest of the page can be cached
• Controllers & scripts — profiling with the B2C Commerce code profiler, removing redundant API calls, respecting quotas and timeouts
• Integrations — caching, timeouts and graceful fallbacks for payment, tax, search and inventory services
• Jobs & feeds — scheduling and tuning imports and exports so they never compete with checkout traffic
• eCDN — cache rules and asset delivery tuned to your catalogue and markets

Peak readiness

• Load testing against realistic traffic profiles before major campaigns
• Runbooks for sale launches, drops and Black Friday
• Monitoring & alerting so regressions are caught in minutes, not in next week’s conversion report

How an engagement works

1. Measure

We start with field data — how real shoppers experience your storefront across devices and markets — and pair it with lab traces and server-side profiling to find root causes, not symptoms.

2. Prioritise

You get a clear list of findings ranked by impact and effort, with the evidence behind each one. No 80-page PDF; a backlog your team can act on.

3. Fix

Our certified SFCC engineers implement the fixes — or pair with your team and incumbent partner to do it together.

4. Guard

We put performance budgets into your delivery pipeline and monitoring, so the gains survive the next campaign, redesign and integration.
