> Improve FUSE IO performance by supporting FUSE parameter max_background
> -----------------------------------------------------------------------
>
> Key: HDFS-16403
> URL: https://issues.apache.org/jira/browse/HDFS-16403
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: fuse-dfs
> Affects Versions: 3.3.0, 3.3.1
> Reporter: daimin
> Assignee: daimin
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 2h

> When we examining the FUSE IO performance on HDFS, we found that the
> simultaneous IO requests number are limited to a fixed number, like 12. This
> limitation makes the IO performance on FUSE client quite unacceptable. We did
> some research on this and inspired by the article [Performance and Resource
> Utilization of FUSE User-Space File
> Systems|https://dl.acm.org/doi/fullHtml/10.1145/3310148], clearly the FUSE
> parameter '{{{}max_background{}}}' decides the simultaneous IO requests
> number, which is 12 by default.
> We add 'max_background' to fuse_dfs mount options, the FUSE kernel will take
> effect when an option value is given.
