Hi Please suggest nfs and cifs bench mark tools for freeNAS..also provide us the steps to install

Similar to what you asked previously:
http://www.linuxquestions.org/questi...ce-4175530414/

..which gave you one answer. Also, you can find MANY ways to measure this with a brief Google search. Please read the "Question Guidelines" link in my posting signature. Asking us to look things up for you, hand you links, and give you a step-by-step guide is fairly rude.

Try putting "how to benchmark nfs performance in linux" or "how to benchmark cifs performance in linux" into Google...amazingly, you'll find MANY suggestions. The dbench utility is only one. Creating a large file and just copying it and timing it is another very simple thing too.
