In a series of local benchmarks on a 2.6 GHz six‑core Intel i7 machine, the author compares K6, Gatling, and FunTester under 10 k to 20 k QPS loads, detailing CPU, memory, and response‑time metrics, analyzing script languages, JVM settings, and offering optimization suggestions for FunTester.
A recent offline performance test of a Dubbo service revealed that enabling Logback’s default packageData option caused massive AladdinClassLoader lock contention, dramatically increasing response times, and the issue was fixed by upgrading Logback to a version where packageData is disabled by default.
Gatling‑Dubbo 2.0 is a Gatling‑based load‑testing plugin that replaces generic Dubbo invocations with real API calls, offering richer scenario orchestration, traffic models, native throttling, lower resource use, and higher concurrency, while providing Action, Check, and DSL components illustrated through a complete mixed‑scenario simulation.
MAXIM is Youzan’s distributed full‑link load‑testing engine built on Gatling, featuring a central control center, multiple load injectors, a GUI for test orchestration, data‑parameter binding, real‑time injector monitoring, automated reporting with historical retention, and extensible architecture supporting Dubbo and centralized InfluxDB logging.
The Gatling‑Dubbo plugin extends Gatling’s high‑performance, event‑driven load‑testing framework with a Dubbo protocol layer, providing protocol, action, and JsonPath‑based check components plus a HTTP‑like DSL, enabling asynchronous generic calls, response validation, throttling, and full example simulations for distributed Dubbo service testing.
Youzan’s full‑link load‑testing architecture combines a traffic generator, a data‑factory pipeline, and the Maxim platform to replay realistic e‑commerce user actions, tag and isolate test traffic via unified headers, route reads/writes to shadow storage, and integrate Gatling for capacity planning, degradation, alarm, disaster‑recovery and throttling drills.
