Using readdir rather than readdir plus is faster in this case. === NFS v4 === * [[File:v4_ls_f_noplus_real.jpg]] * [[File:v4_ls_f_plus_real.jpg]] == Sys == === NFS v3 === * [[File:v3_ls_f_noplus_sys.jpg]] * [[File:v3_ls_f_plus_sys.jpg]] === NFS v4 === * [[File:v4_ls_f_noplus_sys.jpg]] * [[File:v4_ls_f_plus_sys.jpg]] ** Unmodified 2.6.38 gives the worst performance here.
