Who is this for?
This is an advanced topic for engineers who want to tune the performance of network workloads on Arm Neoverse-based bare-metal instances.
What will you learn?
Upon completion of this Learning Path, you will be able to:
- Set up Apache Tomcat and wrk2 to benchmark HTTP on an Arm Neoverse bare‑metal host
- Establish a reproducible baseline baseline (file‑descriptor limits, logging, thread counts, fixed core set)
- Tune NIC queue count to match available cores and measure impact
- Improve NUMA locality by placing Tomcat on the NIC’s NUMA node and aligning worker threads with cores
- Compare IOMMU strict mode and IOMMU passthrough mode, and select the configuration that delivers the best performance for your workload
Prerequisites
Before starting, you will need the following:
- An Arm Neoverse-based bare-metal server running Ubuntu 24.04 to run Apache Tomcat
- Access to an x86_64 bare-metal server running Ubuntu 24.04 to run
wrk2 - Basic familiarity with Java applications
