To throttle the CPU only and not the network, go to the Performance panel, click Capture Settings, and then select 4x slowdown or 6x slowdown from the CPU list.

Keep in mind that the throttling is relative to the normal capability of your laptop or desktop. Low-end mobile simulates slow 3G and throttles your CPU 6 times slower than normal. Mid-tier mobile simulates fast 3G and throttles your CPU so that it is 4 times slower than normal. To throttle both the network and CPU, select Mid-tier mobile or Low-end mobile from the Throttle list.
