The cd-rom's maximum speed will 150 kps times it's rated max. So if it is a 4x cd-rom, then it's maximum transfer rate is 600 kilobytes per second. 10baseT Ethernet is generally has a greater transfer rate than older cd-roms up to about 8x. In addition, the Mac file system is somewhat inefficient, especially on cd-roms. The OS may need to seek around the cd-rom, which is very slow (up to 1 second average seek time on older CD-ROMS). When you move the contents to the hard drive, then do the copy, you are drastically decreasing the seek times and probably increasing the transfer rate from the drive. At that point, the network connection would be the bottleneck. ===== ----------------- Ed Murphy [EMAIL PROTECTED] __________________________________________________ Do You Yahoo!?
