I am using xfs filesystem and also did the fsck. DMA is enabled.
Also perfomed xfs defragmentation( xfs_fsr). But still an issue not only rm

Until quite recently XFS was notable for being slow to delete. Othershave noted that this is greatly improved in recent kernels but even witholder kernels there is quite a bit of tuning that you can do to improvethe delete performance. Your favourite search engine should giveyou good results.


I put down some notes for myself here a while back:
