Usually (untuned), you don't get much more on a 100MBit system. If you tune it
(set e.g. rsize/wsize to more reasonable values), you get a speedup to around
3MB/s (at least that's what I experienced), while with FTP you get around
8-9 MB/s. The servers were 4x Xeon with 2GB of RAM and Hardware RAID5, the 
clients usually PIII/450.
