My FTP speed is also slow. I connect via crossover cable directly from PC to PS3. When I was on multiman 4.16.0 I would get up to 10Mbps. Now that I'm on 4.18.04 I get up to 5Mbps. I avg. 1-2Mbps btw. Avg 7GB backup game I can ftp in 3-4 hours depending on number of files/folders.
FlashFXP 4.2.2, 100 Full-Duplex on NIC, Crossover network cable.
