@wangxuemin JuiceFS 对小文件的支持还是可以的,你用 CV 场景就是海量小文件随机读的情况,请参照我们最新发表的一篇博客: https://juicefs.com/blog/cn/posts/how-to-use-juicefs-to-speed-up-ai-model-training-by-7-times/ 另外,我们也测试了 git 和 源代码编译这类 小文件读写比较多的场景,并作了调优建议: https://juicefs.com/blog/cn/posts/a-case-with-profile-and-stats/ |

bench 就会测试到小文件的读写性能。在没有缓存的情况下,取决于对象存储的读写性能,有缓存的情况下,接近缓存盘的读写性能。
