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
With native winsocket wsttcp (http://www.winsite.com/bin/Info?5896
