Performance Testing in Cardiff
Finding out what your system does under load before your customers do. For Cardiff businesses facing a known peak — a campaign launch, Black Friday, a seasonal surge, a tender that specifies concurrency — we simulate it, find where it breaks, and establish what capacity actually costs.
Why this comes up
The problem
Systems behave completely differently at a hundred concurrent users than at five. The failure point is almost never where the team guessed, and finding it during a real peak is the most expensive possible way to learn it.
What you get
What we deliver
- Load profiles modelled on your real traffic patterns, not a flat synthetic curve
- The breaking point identified, with the specific component that gives way first
- Database, memory and connection limits measured rather than assumed
- Soak testing for the leaks that only appear after hours of sustained load
- Recommendations ranked by cost against the headroom each one buys
- A repeatable test, so the next release can be checked against the same baseline

Thirty minutes, no charge, no sales script. You leave with a written summary of what performance testing would actually involve — whether or not you use us.
Working in Cardiff
Wales
Cardiff has a significant broadcast and media sector alongside a large public-sector presence, and Welsh-language provision is a genuine requirement on public-facing work here rather than a nice-to-have.
Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option.

Performance Testing in Cardiff — common questions
- How do we know what load to test for?
- From your own analytics rather than a guess — peak concurrent users, busiest hour, the ratio of browsing to transactions. Where you are planning a campaign, we test a multiple of your historic peak so you know the margin you have.
- Can you test against production?
- Only with care, and usually we do not. A staging environment matched to production is safer. Where production testing is genuinely necessary it happens off-peak, with rate limits and a stop condition agreed in advance.
- What if it fails much lower than we expected?
- That is a good outcome for a test and an uncomfortable one for a meeting. The report identifies which component gives way, so the fix is targeted rather than a blanket upgrade of everything.
- Is this the same as page speed?
- No. Page speed measures one visitor's experience on an idle system. This measures what happens when thousands arrive at once, which is a different failure mode entirely and needs different work to fix.
- Do you work with businesses across Cardiff?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cardiff businesses do you usually work with?
- Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option. Beyond that we work across Media & Broadcasting, Financial Services, Public Sector, Higher Education and Sport.
- Do you cover the areas around Cardiff?
- Yes — we work throughout Wales, including Bristol, Swansea. Cardiff is an urban area of roughly 490,000+, and we take on work across the wider Cardiff region rather than the city boundary alone.
