TDMS streaming problems

Hi forum,

i have problems streaming a lot of data to a file. I am using  write to measurment file with tdms in the while loop but my pc is to slow to do this streaming (100Ks/s for 10s). 

For optimizing i was thinking to open a tdms file outside the while loop stream it to file in the recording state and then read it to another file in the logging state, clear it and i could stream again.

But can i delate data from the tdms format, or is there something easier to do?

Thanks and best

Martin
