3458A Multimeter slow reading rate

I developed a labview program to read measurements from the 3458A via "read GPIB" command. 
I left all instrument parameters/features in default value, except for NPLC where I set it to 1.

When I measured the reading rate, it takes ~60ms to perform one reading. This seems to be much longer than what I expected.

When I turned the autozero function off, it still takes 40ms to perform one reading. The manual mentions that I should be expecting ~60readings per second, which is about 20ms.

What am I doing wrong?
