One user had similar problems with his Sparc and it turned out the problem was his switches which are auto speed detecting (10/100Mb). The problem was when he plugged a device in to the switch, the switch detected the speed then went into half-duplex mode making Bacula run very slowly. To correct the problem he had to power off the switch then power it back on.
