TUIX v0.6Beta
Performance Architecture
TUIX Core executes critical rendering, compositing, diff computation, and hit-testing in optimized C while Python orchestrates declarative scenes, widgets, and business logic. In v0.6, performance improvements focus on immutable Unicode symbol interning, fine-grained dirty tracking, viewport-aware traversal caching, and zero-allocation frame loops.
Benchmark Suite
The repository benchmark suite tests TUIX against industry alternatives (Blessed, terminal-kit, Ink, ReziTUI, Bubble Tea, Ratatui, OpenTUI, Rich, Urwid, PromptToolkit) across standard workloads.
Performance Characteristics
| Scenario | TUIX Core Timing | Optimization Mechanism |
|---|---|---|
| Startup Initialization | ~286µs - 315µs | Direct native shared library binding and fast registry memory pool allocation. |
| Tree Construction (1,000 items) | ~108µs | Contiguous C array buffer layout with batch UID generation. |
| Incremental Re-render | ~9µs - 15µs | Fine-grained mark_redraw_by_uid dirty tracking and ANSI diff skips. |
| Layout Stress (4 cols x 10 rows) | ~72µs - 81µs | Proportional float geometry calculations resolved in native SIMD/C loops. |
| Full Terminal UI Frame | ~352µs - 413µs | Direct ANSI streaming emission bypassing intermediary string buffer allocations. |
Core Architectural Optimizations
- Interned UTF-8 Symbol Table: 4-byte/interned symbols eliminate heap allocations during text rendering.
- Lock-free Snapshot Reads: Read-only diagnostics and inspections obtain thread-safe snapshots without stalling the render thread.
- Viewport Traversal Caching: Compositor skips off-screen buffer trees and clips geometry before rendering.
- Terminal Probe Cache: Terminal wide-character cell width queries are probed once and cached.
