Performance Workshop: hands-on web performance training
Build performance expertise that stays in-house
Most performance problems come back. Not because the fixes were wrong, but because the team didn't know how to spot the next one coming. This 2-day workshop changes that.
We bring the expertise to you. Your developers leave with the tools, techniques and hands-on experience to identify, fix and prevent performance issues. No agency call needed every time something slows down.
"Everyone learned a lot and I think a lot of performance improvements will be suggested at our clients the upcoming weeks 🚀🚀"

Two days, from fundamentals to hands-on
The workshop moves from theory to practice. Day one builds the foundation - metrics, tooling and the networking layer. Day two is where your team applies it directly to a real website.
Day 1 - Morning: Understanding Web Performance Metrics
- Introduction to web performance optimization
- Setting up your workspace environment
- Which metrics matter and why: LCP, INP, TBT, CLS, TTFB, FCP, SpeedIndex?
- Reading real-user data vs. synthetic tests
Day 1 - Afternoon: Performance Optimization Techniques
- Tools and practices for assessing web performance
- The networking layer: DNS, TLS, HTTP/2, CDN
- HTTP caching: cache-control headers, CDN caching, stale-while-revalidate
- First load performance: render-blocking, critical path
- Hands-on exercises with WebPageTest and DevTools
Day 2 - Morning: Hands-on Optimization
- Image optimization: formats, sizing, lazy loading
- JavaScript and third-party libraries: what's costing you
- Performance monitoring with APIs and RUM
- Live session on a real website
Day 2 - Afternoon: Advanced Strategies and Tools
- DevTools performance panel: reading flame charts and traces
- Critical rendering path, async loading, script strategies
- Performance budgets: setting metric thresholds, measuring against baselines, and keeping regressions out of the backlog
- Recap, Q&A and resources for continued self-study
What participants take home
This isn't a lecture. Participants work through real problems on real websites. By day two they've already applied what they learned.
One e-commerce team left with a full backlog of prioritised issues and resolved all Core Web Vitals problems within a month.
Deep understanding of web performance metrics
Know what LCP, INP, CLS, TTFB and FCP actually mean for users and revenue, not just how to pass a Lighthouse audit.
Practical optimization skills
Hands-on experience applying basic to advanced techniques: images, scripts, the network layer, rendering, and more.
Industry-standard tooling
Confidence with DevTools, WebPageTest, PageSpeed Insights, and RUM - the same tools the experts use every day.
Workshop slides and resource pack
Everything covered in the two days plus a curated collection of resources for continued learning after the workshop.
Real-world experience
Participants work through a live website during the hands-on session - not a demo project, but something they'll recognise from their own work.
A team that can act independently
The goal is reduced dependency on external help. Your team leaves able to diagnose and fix performance issues on their own.
Investment
Starting at €4,000 for a group of up to 6 participants. Includes preparation, two full days on-site, and all workshop materials. Travel costs are billed separately.
Smaller groups get more focused time during hands-on sessions. For larger teams we can split across two dates. Get in touch for a clear quote.
Most teams see the investment pay back within weeks - one meaningful performance improvement often generates more revenue than the workshop costs.
What changes after two days
Before the workshop
- Performance issues are discovered by customers, not the team
- Every regression requires an external consultant or agency call
- Developers don't know which metrics matter or why
- Performance work competes with feature work - and loses
- Nobody can challenge a slow third-party script in code review
After the workshop
- Regressions get flagged before they reach production
- Team triages and fixes issues independently
- Metrics are part of every sprint retrospective
- Performance has an owner and a shared vocabulary
- New scripts and images get reviewed against real thresholds
The expertise you don't have costs you every month
Performance gets worse between deploys. A new script here, an unoptimised image there. Nobody runs a performance check after every feature ship, and unless someone on the team knows what to look for, you find out through your revenue data rather than your monitoring.
The workshop gives your team the tools to catch this before it ships. Regressions get flagged in code review instead of discovered by customers.
FAQ - Performance Workshop
Who is this workshop for?
Senior developers and tech leads who want to move beyond slow sites and vague recommendations. Participants should have a working knowledge of HTML, CSS, and JavaScript. No prior performance experience required - we start from the fundamentals and build up to advanced topics over the two days.
How many people can attend?
The workshop works best with groups of 4 to 6 participants. Smaller groups get more individual attention during hands-on sessions. Larger teams can be split across two workshop dates. We tailor exercises to the specific technologies your team works with.
Do you use our own website during the workshop?
Yes. The hands-on session in day two uses a real website - ideally one your team works on. This makes the exercises directly applicable and means participants leave with insights they can act on immediately, not just theory from a toy project.
Where does the workshop take place?
We come to you. The workshop runs on-site at your office. You need a room with a projector or large display and a stable internet connection. Participants work on their own laptops. We handle all materials and slides.
What's the investment?
The workshop starts at €4,000 for a group of up to 6 participants, including preparation, two full days on-site, and all materials. Travel costs are billed separately. Most teams see the investment pay back within weeks - one meaningful performance improvement often generates more revenue than the workshop costs.
What's the difference between the workshop and a performance audit?
A performance audit is us doing the work: measuring, diagnosing, and handing you a prioritised roadmap. The workshop is about your team building the capability to do this yourselves. Many clients start with an audit to understand the landscape, then do the workshop to make performance expertise permanent in-house.
What do participants take home?
Workshop slides, a curated resource list for continued self-study, and hands-on experience with the specific tools and techniques covered. Participants also leave having worked through real issues on a live website, not just watched demos.
What comes next
The workshop builds the skills. A sprint is how your team puts them to work on your actual site.
Performance Sprint
A focused 2-week sprint to fix your biggest bottlenecks. We work alongside your team using real-user data to ship improvements, not reports.
Performance Audit
A full strategic analysis for complex sites. Real-user data, a business case, and a prioritised roadmap. The right fit when you need a complete picture before committing.
