Hello, I wanted to archive something on my external firewire drive and recognized a massive write performance degradation over 7-current from 3 months ago. I could read _and_ write about 30MB/s, reading still gives me a value like that but writing broke down to 1,4 MB/s!!! Also I see some warnings I haven't seen before:
da4 at sbp0 bus 0 target 0 lun 0 da4: <NEWMOTIO 2045-11 0135> Fixed Simplified Direct Access SCSI-4 device da4: 50.000MB/s transfers da4: 39083MB (80043264 512 byte sectors: 255H 63S/T 4982C) (da4:sbp0:0:0:0): SYNCHRONIZE CACHE.

Possibly that's the culprit? Any help highly appreciated. Thanks, -Harry
