The Question is:
our new AlphaServer DS25, V7.3-2, TCPIP V5.4 downloads a binary file from a
server in a few seconds, uploading the same file takes a very long time. It
ist the same with different servers (VMS and NonVMS). Every outgoing transfer
seems to be slow. If I up
load to DS25 it's fast, download from DS25 is slow.
Any ideas how to avoid this bottleneck?
The Answer is :
Check the Ethernet controller and the switch speed and duplex settings;
ensure the settings match and -- if enabled -- that negotiation has
completed successfully on both ends of the Ethernet network link.

Please also contact your network support organization, as there could
also be hardware-level network error(s) involved here. Also expect to
be asked details of the specific network communications hardware and
the configuration involved here. Also expect to be asked for the
relative time of the longer (outbound) transfer; while longer, the
specific difference -- possibly a factor of about 10? -- could be
of some interest here. (A factor of ten could imply that there is
a negotiation problem involving 10 and 100 megabits, for instance.)
