[GridSim-users] datagrid package - total execution time

Hi good afternoon,

I'm working on the datagrid package of GridSim and I wanted to execute a very
simple simulation with a simple network topology (up to 6 routers) that form a
complete graph of links among them.

But I have a problem with total time execution of the simulation...here you have
some results:

#routers    total exec. time (milliseconds)
2 (1 link)	340
3 (3 links)	380
4 (6 links)	3000    (3 seconds)
5 (10 links)    600000	(10 minutes)

Extrapolating, with 6 routers would be 6 hours, ... with 8 routers (28 links) 52
years! :-S

There is only 1 user, that sends 1 gridlet with a file of 1MB (very simple)

And I'm using a laptop with an Intel Core 2 Duo 2,4GHz processor, and 4GB of RAM.

Could anybody tell if this is normal, and why is it happening?...or better, does
anbydoy know a solution for this, or has any idea?

Thank you very much
