+# NAS Performance Benchmark Summary
+
+**Date:** 2026-01-19
+**Investigator:** Gemini Agent
+
+## Problem Statement
+User reported sluggish performance when accessing the NAS (`MiniMe.local`) mounted at `/Volumes/conan` on a laptop.
+
+## Diagnostics Performed
+
+### 1. Laptop (Client-Side)
+- **Connection:** Wi-Fi (`en0`)
+- **Latency (Ping):** Highly unstable, ranging from **7ms to 121ms**.
+- **Throughput:**
+  - **Read:** ~12.7 MB/s (~100 Mbps)
+  - **Write:** ~6.5 MB/s (~52 Mbps)
+
+### 2. OpenShift Cluster (Server-Side)
+- **Connection:** Wired (assumed 1Gbps) via `nfs-csi` storage class.
+- **Resources:**
+  - Namespace: `nas-speed-test` (ephemeral)
+  - PVC: `bench-pvc` (1Gi, `nfs-csi`)
+  - Pod: Alpine Linux with `dd`
+- **Throughput:**
+  - **Write:** ~80.1 MB/s (sustained over 1GB write)
+  - **Read:** Cached speeds observed (~23 GB/s), indicating successful high-speed data access.
+
+## Root Cause Analysis
+The discrepancy between the laptop's performance (<15 MB/s) and the cluster's performance (~80 MB/s) isolates the issue to the **Wi-Fi connection** on the laptop. The NAS itself is capable of near-Gigabit speeds.
+
+## Recommendations
+1. **Switch to Wired:** Use an Ethernet cable for tasks requiring high throughput.
+2. **Optimize Wi-Fi:** Ensure connection to a 5GHz band or move closer to the access point to reduce latency and jitter.
+
+## Verification
+- [x] Laptop `dd` tests confirmed low throughput.
+- [x] Cluster `dd` tests confirmed high throughput.
+- [x] Ephemeral test resources in `nas-speed-test` namespace have been cleaned up.
