FW: rsync performance

[Dave Mangelsdorf (CBIZ Tech)]

Not sure if this is not the proper channel (forum) for this, but I need some
help.
 
We have been using rsync in various ways on various platforms.
 
Linux-SGI (IRIX)-MacOSX
 
In all cases the actual LOCAL file transfer seems to be limited to 10MB/sec
from disk to disk. Always copy whole files. (no rolling checksums)
 
Rsync –avW
 
rsync  version 2.5.6  protocol version 26
 
We have tested everything from Small I-mac, to 16 processor SGI server with
multiple fibre channel interfaces to very large disk arrays. Always tops out
at 10MB/sec, plus or minus.
 
Normal filesystem copies from raid to raid are in excess of 50MB/sec.
 
Any help would be appreciated
