Very slow writing with tdms of 2d DBL array

[labmaster]

Comparing to saving of waveforms, the 2d DBL array is very and very slow.

For my defined data, 1D waveform took 7 ms, but 2D array (1D: data+1D channel) 4.1 s.

Unfortunately, I can't see the inside of TDMS write.vi.

How can I overcome this trouble, unbelievable performance?

To test other TDMS library, my attachment for LV 2009 requires the user library which can be downloaded from http://zone.ni.com/devzone/cda/tut/p/id/6471.

And what is your reason for trying the G TDMS VIs? I would expect poorer performance with TDMS functions written with LabVIEW code as opposed to the native functions and would only use them on the OS's/LabVIEW versions without TDMS support. You have LabVIEW 2009 so are you trying for other OS support?

I found my mistake.

Too many channels by transposing the array.

Forget my posting. 

I intended to use it under Windows. So you are right.
