Performance issue with C++ ,Socket
Hi all,
I am facing some problem in Socket programming(C++ & Solaris 5.0).I am using socket as
basic connecting point & MEP(Mesagae Exchange Protocol) as high level protocol to send &
receive Message & ACK, between two different system.
MEP is a protocol through which you can send MSG through Socket & wait for the ACK for the
corresponding MSG & go on like this.When I am using our binary(s) between two different
Solaris Box(with diffrent IP) the transfer rate is quite good(Send one MSG & get ACKfor it
takes 1 milisec).
But the problem comes when I use the same binary(s) to do the above MSG processing in
the same Solaris box(with one IP), throughput goes very low (like 50 milisec for each MSG
processing).
I have tried with making the socket to work in non-blocking mod also.But that does not
help at all.
Looking for some quick help & hints to resolve this issue.

socket::getaddrinfo::strict

Socket::GetAddrInfo::Strict(3pm)			User Contributed Perl Documentation			  Socket::GetAddrInfo::Strict(3pm)

NAME

       "Socket::GetAddrInfo::Strict" - Provide Socket::GetAddrInfo functions which throw exceptions

SYNOPSIS

	use Socket qw( SOCK_STREAM );
	use Socket::GetAddrInfo::Strict qw( getaddrinfo getnameinfo );
	use IO::Socket;

	my $sock;

	my %hints = ( socktype => SOCK_STREAM );
	my @res = getaddrinfo( "www.google.com", "www", \%hints );

	while( my $ai = shift @res ) {

	   $sock = IO::Socket->new();
	   $sock->socket( $ai->{family}, $ai->{socktype}, $ai->{protocol} ) or
	      undef $sock, next;

	   $sock->connect( $ai->{addr} ) or undef $sock, next;

	   last;
	}

	if( $sock ) {
	   my ( $host, $service ) = getnameinfo( $sock->peername );
	   print "Connected to $host:$service
";
	}

DESCRIPTION

       Socket::GetAddrInfo provides the functions of "getaddrinfo" and "getnameinfo", which return lists whose first element is error value, or
       false indicating no error occured.

       This module wraps the functions provided by "Socket::GetAddrInfo" to check this error value, and throw an exception (using "die") if an
       error occured.  If not, then the remaining values are returned as normal. This can simplify the logic of a program which otherwise simply
       throws its own exception on failure anyway.

FUNCTIONS

   @res = getaddrinfo( $host, $service, $hints )
       After a successful lookup, returns the list of address structures, as documented in Socket::GetAddrInfo. If the lookup fails, an exception
       containing the string form of the error is thrown instead.

   ( $host, $service ) = getnameinfo( $addr, $flags, $xflags )
       After a successful lookup, returns the host and service name, as documented in Socket::GetAddrInfo. If the lookup fails, an exception
       containing the string form of the error is thrown instead.
