Our “Web performance” expertise

Load testing, RUM and frontend optimisation, APM and code, cache and infrastructure optimisation

Gilles Guirand

Technical Director

Web performance, in the sense of display time & user experience fluidity, is becoming a critical business issue: SEO, user retention, mobile and offline navigation, scalability and peak loads…

Too often focused only on preventive backend load tests and hosting infrastructure, it becomes essential to involve all project teams in a continuous monitoring and optimization process: frontend JS, Google AMP, Real User Monitoring & code profiling.


Load tests

Simulate cohorts and application impact

Load tests simulate and resolve the most salient performance anomalies. Together with our customers, we build the most critical functional scenarios, with JMeter, Gatling or Artillery.


Monitoring & Metrology

APM, code profiling & Real User Monitoring

We supervise with New Relic or AppDynamics all network layers, systems, third-party services, databases, backend application code (APM) and frontend application code (RUM).


PHP & CMS expertise

Drupal, eZ, Symfony, Magento "webperf" audits...

Frameworks and CMS are appreciated for their functional richness, but they are application “millefeuilles” that require a high level of expertise in the optimisation of PHP code, cache, database and third-party services.
