Real

NFS v3

  • V3 ls f noplus real.jpg
  • V3 ls f plus real.jpg
    • 2.6.38 performs the same as 2.6.36 with the readdir plus cap removed. Using readdir rather than readdir plus is faster in this case.

NFS v4

  • V4 ls f noplus real.jpg
  • V4 ls f plus real.jpg

Sys

NFS v3

  • V3 ls f noplus sys.jpg
  • V3 ls f plus sys.jpg

NFS v4

  • V4 ls f noplus sys.jpg
  • V4 ls f plus sys.jpg

RPC ops

NFS v3

  • V3 ls f noplus rpc.jpg
  • V3 ls f plus rpc.jpg

NFS v4

  • V4 ls f noplus rpc.jpg
  • V4 ls f plus rpc.jpg
