I doubt a gigabit Ethernet connection will make any significant difference. Data rate from your scanner is dependent on the mechanical speed of the sensor and scan resolution. If you scan a page 8.5 by 11 inches at 600 pixels per inch resolution with 24 bits per pixel, there is about 100 megabytes of data. With a 100-megabit Ethernet connection, that is about 10 seconds transmission time. If your scanner requires 10 seconds for mechanical movement at that resolution, the Ethernet connection should not limit scan speed.
At 1200 pixel per inch resolution, there would be four times as much data (400 Mbytes.) This would need roughly 40 seconds to transfer using a 100-megabit Ethernet connection, but your scanner likely moves more slowly at that resolution. If you can scan faster than 40 seconds with a USB connection at that resolution, then gigabit Ethernet might help. Do you have any reason to believe your machine even supports gigabit Ethernet? Most do not. Eight seconds instead of two seconds to start a scan sounds like some sort of time-out situation. The tcpdump command could provide some details about timing of the Ethernet traffic, though interpretation of the data might be a challenge. -- sane-devel mailing list: sane-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to sane-devel-requ...@lists.alioth.debian.org
