3) Speed
- - Using the AltRMI over RMI transport as a baseline. Measuring 100,000
- method invocations after discarding the first for the purposes of
- timing, ObjStream over sockets is three times faster, ObjStream over
- Pipe is eleven times faster, Direct is a thousand times faster. Granted
- there could be less of an advantage if compared to a proper RMI solution
- (not layered), or one that is in the same VM with different threads.
-
+ - Counting the number of 'void testSpeed()' invocations in 10 seconds,
+ we can guage the differences (my Athlon900 machine)

- AltRMI can be build easily into any application or application framework.
