Hello,

As I understand this post, this is iperf for esxi? I love this tool, but I don't believe it inside of VM, but on the core!!!

Is there a rookie manual how to install it on existing esxi?

Thanks...

If you just want to do some one time testing you can exact the file and copy in to /sbin or /bin on your ESXi host. If you want to use it long term you would place a copy in /bootbank and /altbootbank, and then modify the modules line in boot.cfg to add a reference to the file.
