Hiding SSID

Read an article on "Is Hiding the Wireless SSID All the Network Security You Need?" by Dale Rapp, which as the title suggests is about the security benefits of hiding the SSID, whilst I take the point the hiding the SSID may improve slightly the security of the wireless network, in my opinion it has a more dramatic affect on the performance of wireless networks than the security benefits the hiding of the SSID brings.
The main affect of hiding the SSID is that wireless clients will not see the wireless network as the broadcast function is turned off, other mechanisms that will give out the SSID are still in play and used by those interested in breaking into a wireless network.
However to many domestic users of wireless networks the problem comes from not being able to see how many networks are on a channel if the some of the networks are suppressing the broadcast of the SSID. The upshot is that often when the RF environment is examined there are many networks in close proximity using the same channel, this affects the performance of these networks, and as an increasing number of domestic networks are being used to stream video the affect of the congestion of a channel becomes problem for the users of the network.
This releationship between security and performance is the main focus of the research I am carrying out for my MSc.
