linux - What does the GlusterFS server option cluster.readdir-optimize control? -


i have been trying optimise small file performance of glusterfs storage cluster.

a number of forum threads , blog posts seem suggest setting cluster.readdir-optimize property on volume, like:

$ gluster volume test-share cluster.readdir-optimize on

the default option (as of glusterfs v3.10) seems off, makes me think there must trade-off having feature enabled. however, have not been able find anywhere documentation explaining option does.

i understand function of option before enable in production.
