⚡ Performance Advantages

High-Performance Architecture

BlazeWave's high-performance design eliminates unnecessary memory allocations:

Direct Buffer Access: High-frequency read/write operations bypass intermediate buffers
Memory Pool Reuse: Smart buffer pooling reduces GC pressure

Memory Efficiency

Buffer Pooling: Reusable buffers across connections
Timer Pooling: Reusable timers across connections
GC-Friendly: Reduced garbage collection overhead

High Throughput

High Performance Processing: Optimized message handling pipeline
Sustained I/O: Efficient network I/O processing
Concurrency Optimization: Buffer pool and timer optimization

🚀 Quick Start

Note: The following examples demonstrate standard mode usage. For zero-copy read/write & zero-GC mode advanced usage, please refer to BlazeWave Pulse or check local examples or unit tests.

💡 Tip: Zero-copy read/write & zero-GC mode is achieved by using optimized buffer pools and shared timer pools, suitable for production environments.

Standard Mode

Server

package main

import (
    "context"
    "log"
    "net/http"
    "github.com/heyehang/blazewave"
    // "github.com/heyehang/blazewave/core/pool"  // Required for zero-copy read/write & zero-GC mode
    // "github.com/heyehang/blazewave/core/timer"  // Required for shared timer pool
)

func main() {
    // Standard mode: use default configuration
    server := blazewave.NewServer()
    
    // Zero-copy read/write & zero-GC mode: use custom buffer pools and shared timer pool
    // rPool := pool.NewPool(64, 4*1024)
    // wPool := pool.NewPool(64, 4*1024)
    // sharedTimer := timer.NewTimer(100)  // Shared timer pool with capacity 100
    // server := blazewave.NewServer(
    //     blazewave.WithServerReaderPool(rPool),
    //     blazewave.WithServerWriterPool(wPool),
    //     blazewave.WithServerHeartbeatTimer(sharedTimer),
    // )
    
    server.OnTextMessage(func(ctx context.Context, conn *blazewave.Conn, payload []byte) error {
        log.Printf("Received: %s", string(payload))
        return conn.Write(ctx, blazewave.MessageText, payload)
    })
    
    http.HandleFunc("/ws", func(w http.ResponseWriter, r *http.Request) {
        conn, err := server.Accept(w, r)
        if err != nil {
            log.Printf("Accept failed: %v", err)
            return
        }
        defer conn.Close(blazewave.StatusNormalClosure, "")
    })
    
    log.Fatal(http.ListenAndServe(":8080", nil))
}

Client

package main

import (
    "context"
    "log"
    "time"
    "github.com/heyehang/blazewave"
    // "github.com/heyehang/blazewave/core/pool"  // Required for zero-copy read/write & zero-GC mode
    // "github.com/heyehang/blazewave/core/timer"  // Required for shared timer pool
)

func main() {
    ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
    defer cancel()
    
    // Standard mode: use default configuration
    client := blazewave.NewClient()
    
    // Zero-copy read/write & zero-GC mode: use custom buffer pools and shared timer pool
    // rPool := pool.NewPool(64, 4*1024)
    // wPool := pool.NewPool(64, 4*1024)
    // sharedTimer := timer.NewTimer(100)  // Shared timer pool with capacity 100
    // client := blazewave.NewClient(
    //     blazewave.WithClientReaderPool(rPool),
    //     blazewave.WithClientWriterPool(wPool),
    //     blazewave.WithClientHeartbeatTimer(sharedTimer),
    // )
    
    // Register event handlers
    client.OnConnect(func(ctx context.Context, conn *blazewave.Conn) error {
        log.Println("Connected to server!")
        return nil
    })
    
    client.OnTextMessage(func(ctx context.Context, conn *blazewave.Conn, payload []byte) error {
        log.Printf("Received message: %s", string(payload))
        return nil
    })
    
    client.OnDisconnect(func(ctx context.Context, conn *blazewave.Conn) error {
        log.Println("Disconnected from server")
        return nil
    })
    
    // Connect to server
    conn, _, err := client.Dial(ctx, "ws://localhost:8080/ws", nil)
    if err != nil {
        log.Fatal("Dial failed:", err)
    }
    defer conn.Close(blazewave.StatusNormalClosure, "")
    
    // Send message
    err = conn.Write(ctx, blazewave.MessageText, []byte("Hello, BlazeWave!"))
    if err != nil {
        log.Fatal("Write failed:", err)
    }
    
    // Keep connection alive for a while
    time.Sleep(5 * time.Second)
}

Performance Optimization Notes:

Buffer Pool Reuse: Shared buffers across connections, reducing high-frequency memory allocations and GC pressure
Timer Pool Reuse: Use WithServerHeartbeatTimer() and WithClientHeartbeatTimer() to share timer pools
Zero-Copy Read/Write & Zero-GC Optimization: Use optimized buffer pools and shared timer pools
