This is well within the capacity of a single 7200 rpm disk and a 10 Mb/S ethernet. (from http://www.oreilly.com/catalog/samba/chapter/book/appb_03.html) Looks like a bottleneck with your system: 1) the MTU is fine, 1500 is the maximum from ethernet. 2) your ftp test showed about 2.2Mbits/s, or 275 KB/S which is suspiciously low. I'd expect between 400 and 1000 KB/S. 3) a single linux server with 10Mb/S ethernet and a 7200 rpm scsi disk should handle 560 KB/S: the bottleneck is usually the disk. Are you running a slow IDE disk, perchance, or two IDE disks on one controller? As to serving 8* 1.5Mbit/S, you need about 1.5 MB/S throughput, which requires a 100 Mbit/S ethernet, 3 7200 RPM scsi disks in a RAID array and a 486 or better CPU (;-)) --dave -- David Collier-Brown, | Always do right.
