Test Environment
Dual-core 2.2 GHz athlon with 2 GB of memory running Windows XP Professional SP3.
Dual-core 2.0 GHz Mac Mini with 2 GB of memory running Windows Vista Ultimate SP1.

 

Compiler
C ++ Visual Studio 2008
C # Visual Studio 2008,. Net version 3.5
Java 1.6.0 JDK

Optimized Compilation speed, 64-bit for VistaCode. Ice 3.30

Latency
Latency is an important factor in evaluating middleware. It is defined as the time when the client calls the server and then receives the result. The minimum latency is defined as the call return time of function o (no input parameter, no return value.

Source code

Ice
Interface latency {
Void O (); // shortest possible operation name
};

WCF
[System. servicemodel. servicecontract]
Interface latency {
[System. servicemodel. operationcontract] void O ();
}

RMI
Import java. RMI. Remote;
Import java. RMI. RemoteException;
Public interface latency extends remote {
Void O () throws RemoteException;
}

 

Test Results

Requests/second	Ice for. net	Ice for Java	Ice for C ++	WCF binary	WCF soap	RMI
Loopback	6,900	8,000	10,500	~ 6,900	~ 2,300	10,600
Gigabit network	2,300	2,300	2,300	~ 2,190	~ 560	2,220

 

Throughput
Another important factor in evaluating middleware is throughput, which refers to the amount of data that the middleware can transmit per second.

Source code

Ice
Sequence <byte> byteseq;
Interface throughput {
Void sendbyteseq (byteseq B );
Byteseq recvbyteseq ();
};

 

WCF
[Servicecontract]
Interface Test {
[Operationcontract]
Void sendbyteseq (byte [] SEQ );

[Operationcontract]
Byte [] recvbyteseq ();
}

RMI
Import java. RMI. Remote;
Import java. RMI. RemoteException;
Public interface throughput extends remote {
Int byteseqsize = 500000;
 
Void sendbyteseq (byte [] SEQ) throws RemoteException;
Byte [] recvbyteseq () throws RemoteException;
}
