|
|
|
### 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)
|
|
