Performance Testing Workshop
A key part of any organization’s testing strategy is the performance test harness. Without access to accurate telemetry and results, it is difficult to reason about the limits of a system’s performance. We place our trust in various tools to place our services under stress, but how can we be sure that the outputs from these tests reflect reality?
This full-day course explores how to validate that your load-testing harness is producing accurate results. Attendees will develop and iterate on a load-test harness to measure the responsiveness of a simple microservice. The course will cover how to measure and report system throughput and latency, and how to measure the system-under-test to understand where bottlenecks lie.
- JVM internals
- System profiling tools
- Benchmarking methods
- Performance monitoring and metrics collection
- High-performance programming techniques
Content & Process
Using an iterative process to performance testing, attendees will learn about JVM internals, advanced profiling techniques, and benchmarking methodology.
This is a hands-on course that will provide tools and techniques for improving application performance.
The extra instructions for attendees is below.
Audience & Requirements
This course is designed for developers with an interest in measurement and testing systems performance.
Workshop attendees should bring a laptop, ensuring that they have the following installed:
Latest _Oracle_ JDK 1.8 (not OpenJDK, not JRE)
Clone the following repository:
This will ensure that project dependencies are already installed on your laptop (further material will be supplied in the workshop).
Linux users can download and build async-profiler, which will be used during the course:
All code samples will work cross-platform, but advanced profiling techniques are only possible on Linux systems.
Attendees running MacOS/Windows should dual-boot to Linux if possible, or run a Linux VM to participate in all exercises.
Some exercises will require a machine with 4 or more hardware threads.
All exercises will be demonstrated by the presenter, so don’t worry if you don’t have a Linux system.
