    Hi all,

    my previous RPC bandwidth problem is in fact a tcp performance problem under cygwin.

    I have compiled ttcp (from
http://programming.ccp14.ac.uk/ftp-mirror/programming/cygwin/pub/cygwin/release/ttcp/) under cygwin

    And I get the following bandwidth (I am on a 100Mbit switched network) !!!

cygwin (ttcp -r -s -fm) <- linux (ttcp -t -s -fm) : 20Mbit
linux (ttcp -r -s -fm) <- cygwin (ttcp -t -s -fm) : 64Mbit
