Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Depends on the hardware where the math is calculated.
How fast is a plain file transfer over simple TCP (netcat/socat,
http-request, or FTP should do it) exact the same link from one DRBD
host to the other??
That should give (roughly) the upper limit of possible speed (and it
ignores DRBD).
