This benchmark compares 6 major Feature Flag SDKs against Switcher Client SDK for Java.
The tests included in this benchmark are focused only on performance and do not reflect nor measure any other SDK capabilities.
The goal is to gain more knowledge and define a baseline to improve Switcher Client SDK overall performance.
Build jar and run the benchmark
mvn clean verify
java -jar target/benchmarks.jar
Tests results are subject to change based on the environment and configuration.
Uses in-memory cache by preloading or using async calls to remote API.
In-memory configuration loaded from a file.
(*) Split SDK does not provide free access to fetch data from remote API - in this test the SDK is returning a default value.
These tests are fully remote.

- when Async, can be up to 6.5x faster than the other SDKs.
- when Local, can be up to 3x faster than the other SDKs.
- 100% remote can only be enabled with Switcher Client and Amplitude Experiment SDKs.
