Case Study: Vocalabs achieves near-instant, GC‑pause‑free reporting and ~7x scalability with Azul Systems' Zing

Vocalabs Scales Mission-Critical Saas Reporting Application With Zing

Vocalabs, a SaaS provider of customer feedback and reporting for Fortune 1000 clients, was experiencing sluggish, interactive reports with occasional multi-minute delays as report sizes and user load grew. The root cause was JVM garbage-collection pauses that forced the team to spend time on performance tuning instead of product features, so Vocalabs turned to Azul Systems and its Zing JVM to resolve the problem.

Azul Systems deployed Zing, which eliminated GC pauses and delivered consistent response times around 6 ms and roughly 7x headroom for growth. The Zing deployment let Vocalabs rebuild reports more often without pauses, provided smoother memory usage and faster production debugging via Zing Vision, improved customer perception with near-instant reporting, and freed developers to focus on features rather than JVM problems.
