Hi Josh,
How is the sustained rate when you simultaneously run
rx_streaming_samples (without dump) and dd?
:-)
Acutally, the result I got is more than unexpected. :o)
Running dd in one terminal and rx_streaming_samples in a second terminal
gives me this:
Terminal 1:
|> dd if=/dev/zero of=/SSD/test2.bin bs=10000K count=100
100+0 records in
100+0 records out
1024000000 bytes (1.0 GB) copied, 19.7982 s, 51.7 MB/s
> dd if=/dev/zero of=/SSD/test2.bin bs=10000K count=100
100+0 records in
100+0 records out
1024000000 bytes (1.0 GB) copied, 14.2399 s, 71.9 MB/s
> dd if=/dev/zero of=/SSD/test2.bin bs=10000K count=100
100+0 records in
100+0 records out
1024000000 bytes (1.0 GB) copied, 10.7249 s, 95.5 MB/s|
Terminal 2:
|./rx_streaming_samples -f 1.575G -d 4 -N 1000000000 -s -o /SSD/test.bin
S|
A single "S" occurrence (!!!) although I used decimation of 4!!! How can
you explain this?
Regards,
Thomas
