True, but... 1 Gbyte in 90 minutes is less than 200 kbytes / second. Bruno: is both reading from and writing to the USB drive slow? How much physical memory do you have installed in the machine? Try to read 100mbytes directly from the raw usb storage device, using different block sizes; how long does it take? # ptime dd if=/dev/rdsk/c6t0d0p0 of=/dev/null bs=8k count=12800 12800+0 records in 12800+0 records out real 14.449 user 0.039 sys 0.345 # ptime dd if=/dev/rdsk/c6t0d0p0 of=/dev/null bs=32k count=3200 3200+0 records in 3200+0 records out real 11.531 user 0.010 sys 0.141 # ptime dd if=/dev/rdsk/c6t0d0p0 of=/dev/null bs=256k count=400 400+0 records in 400+0 records out real 10.706 user 0.002 sys 0.085 This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list [email protected]
