Hi,
We have a sudden increase in the number WLAN users after we embrace BYOD, now WLAn is slow, how would I measure the controller load and traffic to make sure that our controller is resource capable of handling the current traffic/no bottleneck in terms of controller hardware.
Thank you
Take a look at:
show datapath utilization
show cpuload
Also, it also wouldn't hurt to make sure that you are saturating your uplinks into the controllers.

noninterference,
Wifi contention is typically the problem before controller network utlization/resources. A good rule of thumb is to have a gigabit port for each 100 access points you have connected to the controller. Check to see what else could be your bottleneck here: http://community.arubanetworks.com/t5/Technology-Blog/Removing-the-Bottleneck-in-Wireless/ba-p/77978
More data is needed here, what controller, how many ap's, how many users. How is your network designed, could this be a broadcast issue, possibly turning on the BCMC (Broadcast-Multicast) Optimization feature may take care of it?
A 5 minute wireshark while 'parked' on an SSID would be a good idea. Then evaluate the 'pie chart' for proportions of BC, MC, Protocol A, B, C. "Before" info is valuable to have as we manipulate the Nerd-Knobs to tweak performance and gain "After" performance data.
