[comp.os.vms] File transfer speeds accross DECNET

Hopper.XRCC-NS@XEROX.COM.UUCP (06/12/87)

I have a question regarding File transfer speeds accross the DECNET
(Ethernet connection) between a VAX 11/750 and a microVAX II.

We have both a 750 and uVAX on our local Ethernet.  We are running
DECNET on both and find that the speed of communications between the
VAXes is very slow.  I read in the "DEC Professional" magazine  of April
1987 that the file transfer rate between two DECNETted 780's was 40 KB
but that between a QBUS based pdp-11/44 and a 780 was only 10KB.  

Does anyone know if the uVAX to 750 transfer rate is also very low?  If
so, how much is this degraded by having a number of users doing
transfers simultaneously?

Thanks

I can't speak for DECnet between uvaxes, but I've gotten great performance
ftping between uvaxes and between uvaxes and other vaxes, and even between
uvaxes and 20's.  When the net isn't overloaded, I get ~35kb/sec, even
through several routers and bridges.

BTW, the 11/44 is a Unibus, not a Qbus, machine
