I would like to second the request for the capability to measure actual performance of my local network, both the WiFi portion and the wired (Ethernet, powerline) portions. My interest in this capability was piqued by an article in today’s (9/18/2012) Wall Street Journal titled, “Why Wi-Fi Is Often So Slow,” that mentioned one person’s experience improving their network “buying about $400 of Apple Inc. devices that enhance the in-home wireless connection.” I’ve read about Windows-based software for measuring local network performance at http://www.smallnetbuilder.com, but not Mac software. There are professional tools for this purpose, but none that are affordable for home users — and given the Wall Street Journal article, I think there is plenty of latent demand for an affordable LAN measurement software tool for Macs.
