## 性能对比
### 测试环境
| 测试环境 | 详细信息 |
| --------| -----|
| CPU | Intel(R) Pentium(R) G4560 @ 3.50GHz |
| 内存 | 16GB |
| OS | win10 22H2 |
| gcc | mingw (x86_64-posix-seh-rev0, Built by MinGW-Builds project) 13.2.0 |
### 测试方案
```
T0: capacity = 1024, obj_size = 256
T1: capacity = 4096, obj_size = 256
T2: capacity = 8192, obj_size = 256
T3: capacity = 1024, obj_size = 4096
T4: capacity = 4096, obj_size = 4096
T5: capacity = 8192, obj_size = 4096
```
### 测试对比
> 这里是总时间，对比意义不大。而且目前都未使用扩容
1. 链表实现的栈和队列
```bash
function T0 (ms) T1 (ms) T2 (ms) T3 (ms) T4 (ms) T5 (ms)
-------------------- --------- --------- --------- --------- --------- ---------

perf_queue_free() 0.000 0.000 0.000 0.001 0.001 0.001
```
2. 动态数组实现的栈和队列（这里还不涉及到扩容）
