AD215 slew rate

I have made the circuit shown in figure 12 of the datasheet (basic unity gain), with a 2k load. When i see my output i only measure a slew rate of 0.5V/us instead of 6V/us. Is there anything to do to increase the slew rate?

Slew rate is a large signal parameter.  Change the 2k to zero ohms so you don't have an R-C input

and use a signal generator with a very fast rise time, say -10V to +10V in 500 ns or less.

Scope shots of input and output??
