Hardware: 700 GB ATA Raid5 3ware, P4 2.6ghz , 512mb ram I set sector size to 2048, performance increased to 5mb/sec. cmd to creat fs was: newfs -b 16384 -f 2048 -U -m 0.0005% -i 262144 /dev/twed0s1h.bde size of the fs is bout 700GB, inodes should be enough for 45.000 files (there will be big files mostly). tried newfs without -m and without -b -f. No change in performance. do you have any other idea or does 5mb sound about right. Seems awfull slow for a 35mb/s raid. here how I tested: Crypted device: dd if=/dev/zero of=/mnt/test0.trash bs=1024k count=100 104857600 bytes transferred in 19.927204 secs (5262033 bytes/sec) Noncrypted: dd if=/dev/zero of=/test0.trash bs=1024k count=100 104857600 bytes transferred in 2.993742 secs (35025597 bytes/sec) Could anyone tell me if this is supposed to be slow like that ? Or is there anything I missed ? thx alot for you help! Christophe -- Christophe Zwecker mail: doc@zwecker.de Hamburg, Germany fon: +49 179 3994867 http://www.zwecker.de "Who is General Failure ?
