Piotr, One problem is that if you cannot keep up, adding in all-zeros data will just make it harder to keep up. In general, modern PCs should be able to keep up with 25 MS/s without problem unless you are doing a lot of processing. We are actually able to keep up with 300 MS/s on the X300. So the question is more about why the app can't keep up.
An alternative might be to stream to a file. That should keep up without dropping as long as you have a fast drive. Then you can process samples from that file at the pace your app can keep up with.
