1252.0. "FDDI performance and FDDI-EISA board" by ZENA::ASTRUA () Tue Mar 01 1994 08:06

    	I need a document about the TCP/IP performance on FDDI (using AXP
    system) and on Ethernet.
    
    	Could I find it (them) on Easynet ?
    
    	Another question is about the availability of FDDI (tcp/ip) support
    on DEC 2300 AXP system working in DEC OSF/1 (support for FDDI-EISA board).
    
    	Thank you in advance and Ciao. Filippo

    The DEFEA (FDDI EISA) does support OSF/1 and OpenVMS, but check with
    the PM (Sharon Oneill - DELNI::ONEILL) to find out whether your
    particular system is covered.

1252.3Node name doesn't exit !ZENA::ASTRUAWed Mar 02 1994 06:405
    I was not able to reach (node name doesn't exist) the document:
    
    gatekeeper::/pub/DEC/DECinfo/whitepaper/hiperf-tcp.ps
    
    Thank you for your help and Ciao. Filippo.

    That's because gatekeeper.dec.com is the Internet host for customers
    to access the document.  "gatekeeper::" with two colons after it was
    a confusing mistake.  "decwrl" is the Easynet name for "gatekeeper".

    Internally, you can use telnet to reach gatekeeper.dec.com just as
    our customers would.  Or you can access this over Easynet:

	decwrl::"/pub/DEC/DECinfo/whitepaper/hiperf-tcp.ps"
1252.5has DECinfo movedAPACHE::ALLENFri Mar 31 1995 13:236
    Is the hiperf-tcp.ps file still at
    decwrl::"/pub/DEC/DECinfo/whitepaper/hiperf-tcp.ps"
    or has it moved? I tried to copy it and could not find the DECinfo
    directory.

1252.7setsockopt of SO_SNDBUF and SO_RCVBUFAPACHE::ALLENFri Apr 07 1995 12:578
    Thank you for the pointer to pddi-nics.ps. It says 148K socket buffers
    were used to get the highest performance but when I do a setsockopt of
    SO_SNDBUF and SO_RCVBUF of 148K it returns an error of "No buffer space 
    available". It will accept values up to 131K. Is there a way to get the
    148K? I am using OSF V3.2 on an AXP machine.
    
    Thanks,
      Dave
