Pete Wyckoff commented on HADOOP-3805:
--------------------------------------
I should also mention that hdfs_write utility build on libhdfs is no slower
than the shell copy, so the problem is likely not in libhdfs. (based on very
simple tests and Owen also confirmed that he thought libhdfs wouldn't have any
performance issues)
> improve fuse-dfs write performance which is 33% slower than hadoop dfs

> Issue Type: Improvement
> Components: contrib/fuse-dfs
> Reporter: Pete Wyckoff
> Priority: Minor
>
> on hadoop17 running on the namenode/fuse mount point, fuse is 33% slower for
> writing a 1GB file. I don't know right now how to improve this but thought I
> should open up a JIRA for it.
> Note - this benchmark is with no tuning or special fuse config params.
