<div dir="ltr">Hi, Im using Ubuntu 8.04LTS running on IBM x355 1 U server. ( used as a client - accessing NFS large sequential read/write - file size start from 1GB ) I just installed intel 10GB NIC (( using the ixgbe module - using the latest module from intel ) I didnt change any setting of sysctl.conf not any other spacial NFS mount options expect rsize/wsize = 64K The storage is using 10GB as well - there are many spindles so the bottleneck is not their. I managed to write 90MB sec and read 70MB - ( tested with dd + cp ). I wonder what are the recommendations of sysctl.conf or any module options for the ixgbe. I hope im not missing any thing , however i am disappointed from the results. I kindly ask for assistance. Thanks -Erez </div>
