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

What about trying to increase the resync bandwith?
Try changing the common part to something like

common {
        protocol        C;
        syncer  { rate 50M; }
 }

and see what changes increasing again.
You can also set the syncer rate to different values for different resources
In other posts it was also useful to run

drbdadm adjust data1

on both nodes to have modifications in place after changing the config files
