You can check whether such a DNS record exists and points to the correct server using the Linux host(1) command, eg. "host www.testsite.org". If the DNS ...

Thus, when the buffer became full, progress was every time frozen while waiting until the buffer will become empty. After remounting with 'sync' option, the progress start reporting the real speed without any freezes (4-5 MB/sec): sudo mount -o ...

After learning a little about SCHED_BATCH, I wouldn't even attempt to benchmark it: SCHED_BATCH also triggers much longer, batch-like timeslices - the default SCHED_BATCH timeslice is 1.5 seconds. SCHED_BATCH was clearly designed for very long running (hours or even days) compute-intensive jobs. Your jobs are only compute-intensive for seconds or ...
