Hello I've tried to optimize the speed using PPPoEd. I have a FreeBSD Box (5.4) and 4 windoze boxes (win xp, 2000 and 98) Without PPPoEd, the download speed is at 100mbps from FreeBSD box to windows boxes and 80 mbps from a windoze box to another. if i conect all windoze to pppoed freebsd server the download speed from freebsd to windoze is 80 mbps but the speed from one windoze box to another is too slow almost 10 mbps. why is that? If I have 4 or more users the speed slows down at 800 kbps, on a 100 mbps lan (when a user is using ftp to the router). Also when a single user copy a file from router the used CPU is 8%, the router is a Pentium IV at 2,4 Ghz, and it seems too much cpu is consumed. When not downloading files from router the ppp process uses 0% of cpu. i've tried a lot of optimizing solutions but none worked. i've changed MTU, MRU (lower than 1492) from pppoed and tried other pppoed parameters anyone have experience with that? (for windoze box i use pppoe suport from win xp and raspppoe for windoze 2000 and 98) I do not have any pipe, i use a simple firewall with ipfw ovidiu
