I dug a bit deeper, made another test and found out that actually dir2 starts the job a bit later than dir1, but this is a minor difference. What's important is:
1) Both jobs start concurrently on separate directors
2) FD shows both jobs as "running" also
3) Some kind of queue seems to be in effect on FD side:
- log of the job that ended first shows:
28-Nov 23:05 dir1 JobId 83346: Start Backup JobId 83346 ...
28-Nov 23:08 dir1 JobId 83346: Pruning oldest volume ...

29-Nov 13:15 sd1 JobId 83346: Job write elapsed time = 02:29:14, Transfer rate = 164.4 K Bytes/second
- log of the job that ended later shows:

29-Nov 13:24 sd2 JobId 11616: Job write elapsed time = 00:09:24, Transfer rate = 2.611 M Bytes/second
Any ideas what could be happening on FD side for the 2nd job while the 1st one is running?
