chore: update v.mod version

- Increase uSockets listen() backlog from 512 to 16384 in bsd.c
- Add high concurrency test suite (5000-10000 concurrent connections)
- Add HIGH_CONCURRENCY.md documentation with optimization guide
- Add usockets/build.sh script for rebuilding uSockets library
- Update README with latest benchmark results

Performance (macOS M3 Max):
- 5,000 concurrent: 81,524 RPS, 100% success
- 10,000 concurrent: 24,198 RPS, 100% success

System requirements:
- kern.ipc.somaxconn >= 8192
- ulimit -n 65535

+## Build & Run
+
+### Standard Build (picoev backend)
+
+```bash
+v your_app.v -o app.exe
+./app.exe
+```
+
+### High-Performance Build (uSockets backend)
+
+For maximum performance with uSockets backend:
+
+```bash
+v -enable-globals -cc gcc -ldflags "-ldbghelp" your_app.v -o app.exe
+./app.exe
+```
+
+**Note**: The `-enable-globals` flag is required for uSockets backend. The `-ldflags "-ldbghelp"` fixes Windows linking issues.
+
+#### Windows Prerequisites
+
+To use uSockets backend on Windows, you need:
+
+1. **GCC (MinGW-w64)** - C compiler
+   ```powershell
+   # Install via Scoop
+   scoop install mingw
+   
+   # Or via Chocolatey
+   choco install mingw
+   
+   # Or download from: https://www.mingw-w64.org/downloads/
+   ```
+
+2. **V Compiler** - Version 0.4.x or later
+   ```powershell
+   # Install via Scoop
+   scoop install vlang
+   
+   # Or download from: https://vlang.io/
+   ```
+
+3. **Verify Installation**
+   ```powershell
+   gcc --version   # Should show MinGW-w64 GCC
+   v version       # Should show V 0.4.x
+   ```
+
+The uSockets library and libuv are pre-compiled and included in the `usockets/lib/` directory.
+
+### Using uSockets Backend
+
+```v
+import meiseayoung.hono
+
+fn main() {
+    mut app := hono.Hono.new()
+    
+    app.get('/', fn (mut c hono.Context) http.Response {
+        return c.text('Hello, World!')
+    })
+    
+    // Use uSockets backend (high concurrency optimized)
+    app.listen_usockets(3000)
+    
+    // Or use default picoev backend
+    // app.listen(':3000')
+}
+```
+
+See [benchmark/README.md](benchmark/README.md) for performance benchmarks and [usockets/README.md](usockets/README.md) for uSockets integration details.
+
+## High Concurrency Support
+
+v-hono with uSockets backend supports **10,000+ concurrent connections** out of the box.
+
+### Performance Results
+
+| Concurrent | RPS | Avg Latency | P99 Latency | Success Rate |
+|------------|-----|-------------|-------------|--------------|
+| 5,000 | 81,524 | 60.77ms | 295.17ms | 100% |
+| 6,000 | 56,290 | 98.46ms | 557.47ms | 100% |

+| 8,000 | 30,537 | 165.27ms | 1058.05ms | 100% |
+| 9,000 | 28,693 | 215.86ms | 1422.67ms | 100% |
+| 10,000 | 24,198 | 240.90ms | 1602.10ms | 100% |
+
+### System Configuration (macOS)
+
+For optimal high-concurrency performance:
+
+```bash
+# Increase socket backlog limit
+sudo sysctl -w kern.ipc.somaxconn=8192
+
+# Increase file descriptor limit
+ulimit -n 65535
+```
+
+See [docs/HIGH_CONCURRENCY.md](docs/HIGH_CONCURRENCY.md) for detailed optimization guide.

+# v-hono 高并发优化指南
+
+## 概述
+
+v-hono 使用 uSockets 作为高性能网络后端，经过优化后可以稳定支持 **10,000+ 并发连接**。
+
+## 性能测试结果
+
+| 并发数 | RPS | 平均延迟 | P99延迟 | 成功率 |
+|--------|-----|----------|---------|--------|
+| 5,000 | 81,524 | 60.77ms | 295.17ms | 100% |
+| 6,000 | 56,290 | 98.46ms | 557.47ms | 100% |
+| 7,000 | 42,895 | 130.04ms | 824.80ms | 100% |
+| 8,000 | 30,537 | 165.27ms | 1058.05ms | 100% |
+| 9,000 | 28,693 | 215.86ms | 1422.67ms | 100% |
+| 10,000 | 24,198 | 240.90ms | 1602.10ms | 100% |
+
+测试环境：macOS (Apple Silicon M3 Max)
+
+**重要提示**：每次测试后需等待 60 秒让 TIME_WAIT 连接释放，否则会影响下一次测试结果。
+
+## 关键优化
+
+### 1. uSockets backlog 参数
+
+原始 uSockets 库的 `listen()` backlog 参数硬编码为 512，限制了高并发能力。
+
+**修复位置**：`v-hono/usockets/src/bsd.c` (第 532 行和第 578 行)
+
+```c
+// 修改前
+listen(listenFd, 512)
+
+// 修改后
+listen(listenFd, 16384)
+```
+
+修改后的源码保存在 `v-hono/usockets/src/bsd.c`，编译后的库文件在 `v-hono/lib/libusockets_full.a`。
+
+**重新编译**：运行 `v-hono/usockets/build.sh` 脚本。
+
+### 2. 系统参数配置
+
+macOS 需要调整以下系统参数：
+
+```bash
+# 查看当前值
+sysctl kern.ipc.somaxconn
+
+# 临时修改（重启后失效）
+sudo sysctl -w kern.ipc.somaxconn=8192
+
+# 永久修改（添加到 /etc/sysctl.conf）
+kern.ipc.somaxconn=8192
+```
+
+**注意**：实际 backlog 值会被 `kern.ipc.somaxconn` 截断，所以系统参数也需要相应调整。
+
+## 重新编译 uSockets（可选）
+
+如果需要自定义 backlog 值，可以重新编译 uSockets：
+
+```bash
+# 1. 克隆 uSockets
+git clone https://github.com/uNetworking/uSockets.git
+
+# 2. 修改 src/bsd.c 中的 listen 调用
+# 将 listen(listenFd, 512) 改为 listen(listenFd, 16384)
+
+# 3. 编译（macOS with libuv）
+WITH_LIBUV=1 CFLAGS="-I/opt/homebrew/include" make
+
+# 4. 复制到 v-hono
+cp uSockets.a /path/to/v-hono/lib/libusockets_full.a
+
+# 5. 重新编译 v-hono 应用
+v -enable-globals -prod -o your_app your_app.v
+```
+
+## 使用建议
+
+1. **生产环境**：建议使用 uSockets 后端（`app.listen_usockets(port)`）
+2. **系统调优**：确保 `kern.ipc.somaxconn` >= 8192
+3. **文件描述符**：服务器和客户端都需要设置 `ulimit -n 65535`
+4. **启动命令**：`ulimit -n 65535 && ./your_server`
+
+## 高并发测试
+
+运行高并发测试：
+
+```bash
+# 启动服务器
+ulimit -n 65535 && ./bench_server_usockets
+
+# 运行测试 (5000-10000 并发)
+ulimit -n 65535 && go run v-hono/tests/test_high_concurrency.go
+
+# 单独测试某个级别
+ulimit -n 65535 && go run v-hono/tests/test_high_concurrency.go 8000
+```
+
+## 问题排查
+
+如果高并发测试失败，检查：
+
+1. 服务器是否正常响应：`curl http://localhost:8080/health`
+2. 系统参数：`sysctl kern.ipc.somaxconn`
+3. 文件描述符限制：`ulimit -n`
+4. 测试客户端是否有端口耗尽问题
+
+## 版本信息
+
+- uSockets backlog: 16384
+- 测试日期: 2026-01-03
+- 测试通过最大并发: 10,000（不使用渐进式启动）

+| 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:
+
+```bash
+# 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
+
+```v
+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
+
+```bash
+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)
+
+1. **GCC (MinGW-w64)**
+   ```powershell
+   scoop install mingw
+   # or
+   choco install mingw
+   ```
+
+2. **V Compiler** (0.4.x or later)
+   ```powershell
+   scoop install vlang
+   ```
+

+## Configuration
+
+```v
+// Custom configuration
+app.listen_usockets_with_config(meiseayoung.hono.UsocketsConfig{
+    port: 8080
+    host: '0.0.0.0'
+    keepalive_timeout: 30
+    max_keepalive_req: 10000
+})
+```
+
+## 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)
