I just installed MacOS 9 on an iMac DV SE last week. I've set up file sharing and can see it from other systems on the network, all using MacOS 8.6. One system, a PB 1400/250 is connected to the 10/100 ethernet hub at 10 Mbps, the rest are at 100 Mbps. Unfortunately, the sharing is extremely slow from the PB 1400, but the other systems seem as fast as ever. What used to take a second to open a folder from the PB to the iMac now takes about 30 seconds. The problem appears to be the same whether TCP/IP sharing is enabled or not. The iMac doesn't seem affected by this, just the PB trying to share files from it. I checked the MacFixit and MacNN forums, but didn't find anything that clued me in. One suggestion was to trash the AppleShare PDS file on the iMac and let it get rebuilt. No change. Anyone have any thoughts on this?
