用国内某个厂商的对象存储作为后端存储,它的大对象延时达到100ms,我如何提升我的读吞吐? #6207

你好,我应该如何设置可以提升读吞吐? 如果告诉我怎么调整,我想顺带问一下这样调整会有什么负作用?或者风险影响?会不会cpu飙升 cpu sys上涨之类的? juicefs后端是异步去拉数据还是同步线程去对象存储拉数据? 非常感谢 |

一般读取速度是受限于对象存储的,建议先用objbench压测一个基准性能,然后再调优,比如可以尝试加大预读和缓存看看, |

max-readahead
和buffer-size
;你也可以看看https://juicefs.com/docs/zh/community/architecture和https://juicefs.com/docs/zh/community/internals/io_processing了解IO的流程。
