We evaluated response time in a simple application and it seems that 
a single call may take about 20 milliseconds on Alpha 300MHz.  If we 
establish the connection to the server beforehand, it goes down to 
10 milliseconds.  

Comparing to the response time of simple socket communication, which 
is less than a millisecond, it's somewhat slow.  We use DEC's CORBA, 
ObjectBroker.  If you use other implementations, it may give better 
results. 

Regards, Kazuro.
