cmd 支持不同格式输出 - 方案性能对比

test.markdown

简单的测试了下时间，目前 4k 首歌曲，大概是这么个情况。

In [16]: start = time.time()
    ...: get_dumper('json').dump(songs)
    ...: print(time.time() - start)
0.3063631057739258

In [17]: start = time.time()
    ...: get_dumper('json').dump(songs)
    ...: print(time.time() - start)
0.14913415908813477

In [11]: start = time.time()
    ...: get_dumper('plain').dump(songs)
    ...: print(time.time() - start)
0.4179658889770508

In [12]: start = time.time()
    ...: get_dumper('plain').dump(songs)
    ...: print(time.time() - start)
0.17125320434570312

但如果使用 fuo show fuo://.../songs，实际上缓存会失效，因为 model 不是同一个。
