I agree with Nick: that VOLK stuff is all expected behavior. If you're trying to write to a file at high rates you should look in to using a ramdisk/tmpfs. You'll be limited by how much RAM you have rather than IO speed.
However, based on your other threads I wonder if you've taken Tom's recent suggestion to just lower your input sampling rate? If you're only interested in ~1MHz bandwidth you shouldn't be sampling at 50 MHz. -nathan On Mon, Nov 25, 2013 at 12:08 AM, Nick Foster <bistrom...@gmail.com> wrote: > Your file sink only records a few seconds of data because your hard drive > can't keep up, not because of any problem with Volk.
