## README

# 1. 项目名称
    C++实现高并发内存池:仿google开源项目tcmalloc
# 2. 项目简介
    1. 仿照tcmalloc三重缓存设计,并引入基数树结构优化,项目内部使用自身设计定长内存池全面替代new/malloc
    2. 项目在高并发,小内存,高频次,短生命周期的内存申请场景中,测试性能优秀,整体性能在malloc的1.5~2倍之间
    3. 项目兼容Linux中32bit或64bit开发环境,暂不支持Windows环境,请注意
# 3. 快速开始
    git clone https://gitee.com/wu-nuofan/concurrent-memory-pool.git
    cd concurrent-memory-pool/my-tcmalloc/
    make output
    此时已自动将内存池打包成动静态库形式,分别在当前目录下的DynamicLib和StaticLib下(32-bit，64-bit)
    同时已将所有头文件放在当前目录下的Header下,使用时包含ConcurrentAlloc.h头文件,使用ConcurrentAlloc进行内存申请和ConcurrentFree进行内存释放

# 4. 简单性能测试

## 4.1 测试结果

| Test Case | Size (bytes) | MyMalloc | System Malloc | Improvement |
|-----------|-------------|----------|---------------|-------------|
| different thread_5 | Mixed | 713.5 μs | 1.7 ms | **+58.1%** |
| different thread_1 | Mixed | 17.8 μs | 32.1 μs | **+44.5%** |
| different memory allocation | 2048 | 1.5 ms | 2.1 ms | **+29.1%** |
| different memory allocation | 524288 | 22.9 μs | 7.0 μs | -228.4% |
| different frequency_100000 | Mixed | 656.5 μs | 1.2 ms | **+43.0%** |
| different frequency_1000 | Mixed | 8.0 μs | 4.3 μs | -88.5% |
| different life period | Mixed | 188.0 μs | 1.1 ms | **+83.3%** |

## 4.2 总结

- **different thread performance**:better than system malloc
- **small memory performance**:better than system malloc
- **big memory performance**:worse than system malloc
- **different life period performance**: better in short life than long life
