The problem about execution time of calling labview_dll in cvi . Urgent . Thanks

Hello

I read data from FPGA in labview with three host-vi . Then package  three host-vi to generate dll . When calling dll in CVI to read data,I  find the call time will reach more than 70~200ms. How caused this time ,is there any way reduce this time ?  

 

Thank you

Maybe the time was spent on the entering of dlls,every time I want to get data from FPGA, I would have to first enter the dll, then excute the dll, read data from FPGA, then send them from dll to CVI, that's a time consuming work。

How can I reduce the time?

If I can enter the dll only one time at programme beginning , then only read data each time . The time will be a little . How can I  do this ?
