 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.
 
 learning_objectives: 
-    - Set up a benchmarking environment using Tomcat and wrk2
-    - Set up a baseline performance configuration before tuning
-    - Tune network workloads performance using NIC queues 
-    - Tune network workloads performance with local NUMA
-    - Tune network workloads performance with IOMMU
+    - Set up a benchmarking environment using Apache Tomcat and wrk2 on an Arm Neoverse bare‑metal host
+    - Establish a reproducible baseline performance configuration (throughput and latency) before tuning
+    - Tune NIC multi‑queue, RSS/RPS/XPS, and IRQ affinity to increase throughput and stabilize latency
+    - Optimize NUMA locality by pinning Tomcat workers and interrupts to local CPUs and memory
+    - Evaluate IOMMU configuration options and select the setting that maximizes networking performance
 
 prerequisites:
-    - An Arm Neoverse-based bare-metal server running Ubuntu 24.04 to run Tomcat. This Learning Path was tested with an AWS c8g.metal-48xl instance
-    - Access to a x86_64 bare-metal server running Ubuntu 24.04 to run wrk2
+    - An Arm Neoverse-based bare-metal server running Ubuntu 24.04 to run Apache Tomcat (this Learning Path was tested with an AWS c8g.metal-48xl instance)
+    - Access to an x86_64 bare-metal server running Ubuntu 24.04 to run wrk2
     - Basic familiarity with Java applications
