DMA Speedtest Memflow RS

Windows GUI for benchmarking DMA read performance through the memflow framework. Targets explorer.exe/ntdll.dll and reports throughput, read rate, and latency in real time.

Features

• PCILeech and memflow-native connectors
• Batch testing across configurable read sizes
• Live plots for throughput, reads/s, and latency with per-size summaries
• Embedded console, adjustable UI scale, and resizable plots

Build from source

git clone https://github.com/sh1ftd/dma-speedtest-memflow-rs.git
cd dma-speedtest-memflow-rs
cargo build --release
./target/release/dma-speedtest-memflow-rs

Usage

1. Launch the binary.
2. Pick a connector:
   • PCILeech (requires hardware device identifier)
   • Native (memflow-native for local testing)
3. Set test duration (1–60 s) and enable desired read sizes.
4. Start the test, observe results.

UI Overview

• Configuration: connector selection, duration slider, read-size grid with bulk actions, UI scale input.
• Results: throughput/reads/latency plots, min/avg/max tables, live metrics banner, chunk progress, console toggle.
• Console: optional overlay listing size transitions, stats updates, and errors.

Requirements

• Windows 10/11 64-bit
• Rust toolchain for local builds
• PCILeech-compatible hardware and drivers for physical testing
