- Organize lib directory by platform: windows/, macos-arm64/, macos-x64/, linux/ - Update build.sh to support unified build process for Windows/macOS/Linux - Compile libuv + uSockets and merge into complete static library - Update usockets.v conditional compilation to point to new directory structure - Optimize benchmark tests with connection pooling for high concurrency testing - Clean up unused legacy library files Performance test results (Windows): - 1000 concurrent, 1M requests: 35,223 req/s - 10000 concurrent, 1M requests: 26,884 req/s
uSockets Backend for V-Hono
High-performance server backend using uSockets library.
High Concurrency Performance
The included libusockets_full.a has been optimized with backlog=16384 to support high concurrency:
| Concurrent | RPS | Success Rate |
|---|---|---|
| 4,000 | 112,614 | 100% |
| 6,000 | 56,728 | 100% |
| 8,000 | 33,255 | 100% |
| 10,000 | 25,964 | 100% |
System Requirements
For 10,000+ concurrent connections:
# macOS
sudo sysctl -w kern.ipc.somaxconn=8192
ulimit -n 65535
# Linux
sudo sysctl -w net.core.somaxconn=8192
ulimit -n 65535
Performance
Based on benchmark tests (200 connections, 100K requests):
| Backend | RPS | Avg Latency | P95 | P99 |
|---|---|---|---|---|
| uSockets | ~22,000 | 8.75ms | 16.66ms | 25.73ms |
| picoev | ~15,000 | 13.36ms | 18.89ms | 31.66ms |
uSockets provides ~50% higher throughput under high concurrency.
Usage
import meiseayoung.hono
fn main() {
mut app := hono.Hono.new()
app.get('/', fn (mut c hono.Context) http.Response {
return c.text('Hello from uSockets!')
})
// Use uSockets backend
app.listen_usockets(3000)
}
Build Command
v -enable-globals -cc gcc -ldflags "-ldbghelp" your_app.v -o app.exe
Required flags:
-enable-globals- Required for uSockets global state-cc gcc- Use GCC compiler (MinGW-w64 on Windows)-ldflags "-ldbghelp"- Fix Windows linking (Windows only)
Prerequisites (Windows)
-
GCC (MinGW-w64)
scoop install mingw # or choco install mingw -
V Compiler (0.4.x or later)
scoop install vlang

Notes
- On Windows, uSockets and picoev have similar performance
- On Linux, uSockets may have greater advantages due to epoll optimization
- uSockets excels under high concurrency (200+ connections)
