HMC784A significant gate lag

The HMC784A data sheet indicates 112 ns switching time (10% to 90% RF) with VCTRL & VDD of 5 V. 


I'm getting much longer switching times, on the order of 2 us.  I'm using it at VCTRL & VDD of 8 V.  I assume this is GaAs gate lag?  Do you have any switching speed data for 8 V operation.  My drivers are plenty fast enough.
