DMA using 'nano itx s6 development kit' through PCIe bus

hello,

 

My requirment is to acquire continuous data from FPGA to system. for that i have used Nano ITX/ s6 development board. i want to do DMA continuously  through PCIe bus. I ahve used Windows embedded 7 as opearting system. and loaded deveice driver. and User interface is through BMD - TX engine.

i am able to do DMA once. and the size of one DMA is 32 k. but for next DMA program it is wait and after approximately 1 sec it start again for next DMA. how to reduce time between DMA.
