direct links of old sources may well be a few messages off.


the troughput is NOT 12kb/s, it is 12000kb/s. I had read it wrong, because
12,123 looks for me like 12 and not like 12000. But this is almost slow.
The harddisks can do 25MB/s and the network is a directly gigabit
connection. I use RAID 5 too with a 3Ware Escalade 7506-4P and three
Seagate Baracuda 160GB harddisks. A fullsync takes round about 6 hours.
Thats OK, but it could be better, because the 12000kb/s are less than 50
percent of the speed that theoretically must be usable.
