Yesterday, I installed an Ethernet card and the corresponding EtherTalk
software on my Mac IIcx in the hopes that it would increase my TOPS access
speed.  I noticed no improvement over AppleTalk while using TOPS, but did 
notice a difference using Su-Mac for FTPs (27000 bytes/sec for EtherTalk
and 4000 bytes/sec for AppleTalk).  What I am doing is putting a FoxBASE
database on a TOPS volume that exists in my home directory on one of our 
Sun4's and opening it up using FoxBASE on my machine.  It takes basically the
same amount of time for AppleTalk and EtherTalk (this shouldn't be true).

Does anyone know is TOPS is limited to AppleTalk speeds internally?  I noticed
that Telnet is limited to AppleTalk speeds for FTP, because it transfers at
the same rate, while Su-Mac was flying under EtherTalk.

If you have any suggestions or ideas, please respond via e-mail

Thank you for any and all help provided.
