Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 776 Lines: 18 I have very very fast network and is testing NFS2 over this kind of network. I noticed that for standard work like read/write a large file, compile kernels, the performance of NFS2 is good. But if I try to decompress kernel tar file. The standard ext2 takes 28s while NFS2 takes 81s. Also, if I remove the kernel source code tree, ext2 takes 19s but NFS2 takes 44s. Why? (You can assume that network is very fast. ) Is there any improvements in NFS3/4 on this issue? If so, how?
