H A Dnfsd-io-modes.rst12 to override that default to use either DONTCACHE or DIRECT IO modes.
48 the benefits of using DIRECT IO without any of the strict alignment
49 requirements that DIRECT IO imposes. To achieve this buffered IO is used
71 NFSD DIRECT
74 DIRECT IO doesn't make use of the page cache, as such it is able to
80 system memory. The pathological worst-case workload that NFSD DIRECT has
83 The reason for such improvement is NFSD DIRECT eliminates a lot of work
86 using NFSD DIRECT, kswapd and kcompactd are no longer commanding CPU
90 The performance win associated with using NFSD DIRECT was previously
96 - NFSD DIRECT can significantly reduce memory requirements
