[ndnSIM] delay tracer

[ioannoa]

Hello everyone,

I just got some results from an ongoing simulation which look quit 
weird, thus i though you may give me a hind.

I tested two caching algorithms, one actually performs no caching at 
all and the other does. The weird thing is that in some cases I have the 
no caching one resulting in less delay than the one that performs 
caching. The only possibility i can think of where this is possible is 
if the lookup in the Content Store is added to the final delay seen by 
the application. Does this hold?

Many thanks in advance!

Kind regards,
Andriana.
