# 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.
