Delta Printer + Repetier Firmware v091 slow.... How do I increase print and movement speed?

Hi,
I'm in the process of building a Rostock style Delta printer with the configuration as attached. I have Nema 17 60mm motors for all axis's driven by RAMPS 1.4 controller + 430W power supply.
I have the power supply, controller and motors hooked up for firmware calibration/setting and I'm using Repetier firmware v091. I'm using the Repetier Host v0.95D to 'Dry Run' a test print.
The stepper drivers (A4988) are set at 1/16 microstepping (all three jumpers installed).

The three sets of pillars are 700mm high carriage movable; the centre of the pillars are 530mm to each other; the diagonal rod is 435mm ball centre.

The problem is that the motors are running at super slow mode during dry run and positioning (at around 3~4 seconds a quarter turn of the motor).
Could anyone please help troubleshoot my configuration so that the print could run fast (lets start with the Dry Run mode)?
Thanks.

#define MAX_FEEDRATE_X 300
#define MAX_FEEDRATE_Y 300
#define MAX_FEEDRATE_Z 2
#define HOMING_FEEDRATE_X 300
#define HOMING_FEEDRATE_Y 300
#define HOMING_FEEDRATE_Z 2

change to

#define MAX_FEEDRATE_X 300
#define MAX_FEEDRATE_Y 300
#define MAX_FEEDRATE_Z 300
#define HOMING_FEEDRATE_X 80
#define HOMING_FEEDRATE_Y 80
#define HOMING_FEEDRATE_Z 80

Thanks for the reply but I'm getting the same speed on the motors as before.

Any other ideas?

All good now. I've missed the acceleration settings! Doh!

I've set mine to test at the following settings and the speed looks ok. Thanks for your input Xabbax.
