Performance testing

Performance testing services for SaaS traffic spikes

Performance testing services prove your release survives real traffic — not just a happy demo. TestSync Lab runs load spot checks and p95/error-rate style gates (JMeter-based profiles) on Scale retainers for USA and global SaaS teams. Also see /services/performance-testing and /load-testing-services.

Why SaaS teams hire TestSync Lab

  • Spot checks that inform go/no-go

    Targeted load on critical APIs/journeys — not a month-long perf program by default.

  • Bottleneck notes for eng

    Actionable findings, not only charts.

  • On Scale (or scoped Enterprise)

    Performance depth sits in Scale ($2,799) or custom scopes — keep Basic/Growth honest.

Problems this retainer replaces

  • Launch day meltdown

    A pre-launch spot check beats learning p95 in production.

  • Perf theater with no release gate

    We agree what fails the ship decision before the run.

  • Only UI load tools

    API-level load often finds the real bottleneck faster.
