- You can install a FDDI card in both the PC and SUN and get ~10MB/s.
-
- I normally transfer 16MB images from PC<==>Sparc2 and Sparc10 and I get about
- 1.5MB/s. I have the WD 16bit cards and just run NCSA FTP.
-
- Do you have lots of traffic on your ethernet? if so, then you might be able
- to install a dedicated NIC not necessarily a FDDI but a dedicated ethernet.
