Oscilloscope card (PCI-5105) capture waveform data speed problems

[多多]

Hello, 
Attached file, and the bottom two Pictured vi

NI PCI-5105 oscilloscope card has 8 input channels, 60M / s sampling rate

then input waveform frequency of this oscilloscope card for 4M / s
I want to capture 10000  waveform data in 1 second then convert array for processing 
But I took about 5 seconds to complete (as shown in the red)
how do I reach my goal?
Thank you for your help

I would say your benchmark is flawed.  You time is also including the setup time, which can take quite awhile.  Use a flat sequence structure to have you discrete steps (setup, start time, capture data, stop time).  Try this as a benchmark baseline.

HI

I use your method,

but the elapsed time still about 5 second
