HaikuBench v1.1.0

What's New in v1.1.0

New Features

• 2D hardware acceleration detection — identifies the active accelerant driver via BScreen::GetDeviceInfo() and ioctl B_GET_ACCELERANT_SIGNATURE, reports FillRect/ScreenBlit/InvertRect hook availability
• Adaptive benchmark runner — statistical analysis with CoV, trimmed mean, p50/p95, automatic outlier detection (2-10 runs per test)
• CPU warm-up phase before each test for stable frequency governor
• Real-time temperature overlay on GL benchmark windows
• CPU database for brand string detection
• HaikuPorts recipe for package distribution
• Proper rdef resource file with app_signature, version, and vector icon

Improvements

• Benchmark results now include stddev, median, p95, CoV per test
• zink/NVK compatibility (glFinish before SwapBuffers)
• Fixed race condition in 2D benchmark result caching

Download

• HaikuBench-v1.1.0-x86_64.zip — prebuilt binary for Haiku x86_64
• Or build from source: make && rc -o HaikuBench.rsrc HaikuBench.rdef && xres -o HaikuBench HaikuBench.rsrc

v1.0.1-rc1 — Internal Test Build

Test Build — zink/NVK fix

Changes since v1.0.0

• Add glFinish() before SwapBuffers() in all OpenGL windows (Teapot 3D, GPU Benchmark)
• Add StatsCollector class for system stats monitoring

What to test

• Utenti con zink/NVK (Mesa Vulkan): verificare che le finestre OpenGL (Teapot 3D e GPU OpenGL Benchmark) non siano più bianche
• Utenti con softpipe/llvmpipe: verificare che non ci siano regressioni di performance nella finestra Teapot

Known issues

• CPU Float benchmark counts transcendental functions as single FLOPs (fix planned for v1.1.0)

Changelog

1.0.0 — 2026-03-26

First public release.

System Benchmark (20 tests, 3 runs each)

• CPU: Integer (MOPS), Float (MFLOPS), Multi-thread speedup ratio
• Memory: Sequential Read/Write, Copy (MB/s), Latency (ns)
  • Pointer-chasing with random chain to defeat prefetchers
  • ASM barriers to prevent compiler optimization
• Cache: L1/L2/L3 bandwidth with 8 independent accumulators
  • Batched passes to minimize system_time() overhead on small buffers
• Kernel: Semaphore create/delete/acquire/release/contention,
  Thread spawn, Port send/recv, Area create/delete, Atomic ops,
  Syscall overhead
• Messaging: BMessage flatten/unflatten, BLooper ping-pong

2D Benchmark (24 tests, 6 levels)

• Level 1: FillRect, StrokeRect, FillRoundRect, StrokeLine
• Level 2: FillTriangle, FillEllipse, FillPolygon, DrawString
• Level 3: BShape, gradients, alpha blending, bitmap scaling
• Level 4: 24-point star, clipped regions, conic gradients, text storm
• Level 5: Nebula particles, fractal trees, plasma renderer, everything combined
• Level 6: Full software 3D teapot renderer (wireframe, flat-shaded, x4, x16)
• Two-column layout matching main window style

GPU Benchmark (6 tests, OpenGL)

• Fill rate, geometry, texture upload, alpha blending, stencil, combined stress
• Live rotating teapot preview (Phong shading, 30 FPS animation)
• Fixed 320x240 rendering viewport for consistent results
• GPU Device panel with Vendor, Renderer, OpenGL version, Mesa/driver version

Vulkan Benchmark (4 tests)

• Memory bandwidth (host-visible buffer write)
• Compute shader (1M invocations, 256 FMA/thread, GFLOPS)
• Buffer copy (device-to-device vkCmdCopyBuffer)
• Buffer fill rate (vkCmdFillBuffer)
• Vulkan loaded dynamically via load_add_on (works without Vulkan installed)
• Shader compiled at runtime via glslc (shaderc)

Teapot 3D Benchmark

• 1-64 Utah Teapots via BGLView + glutSolidTeapot
• Real-time FPS counter, add/remove with +/- buttons

Statistics

• Each system test runs 3 times (configurable via kBenchRuns)
• Mean and standard deviation computed per test
• Results displayed as mean +/- stddev in UI and exports

Export

• Markdown (.md) with full results table, machine ID, version, overall score
• JSON (.json) with mean/stddev per test for machine parsing and leaderboards
• Machine ID: FNV-1a hash of CPU + cores + RAM for hardware fingerprinting
• Overall composite score (CPU, Memory, Cache, Kernel, Messaging sub-scores)

Temperature Monitoring

• ACPI thermal zone readout in real-time
• Displayed in main window and as overlay on OpenGL benchmark windows
• Color-coded: green (< 65 C), yellow (65-80 C), red (> 80 C)

UI

• Dark theme (#0D1117) with consistent color palette across all windows
• Monospaced font (be_fixed_font 11pt) for aligned result columns
• BBox panels with titled sections (System, Benchmark Results)
• Section-colored headers, white result rows
• Unified style across System, 2D, GPU, and Vulkan benchmark windows

Packaging

• HVIF icon on binary
• Makefile with src/obj directory structure
• Application signature: application/x-vnd.HaikuBench
