I'm not sure if this should be viewed as a bug or not. It it a problem
for you? It has never been a problem for me.

Some commands have faster method implemented - such as
RandomLinearCode. For most commands, though, it searches some tables
and tries to get estimates for the parameters. I think that is the
part that takes the most time. Removing that would, I think,
require a significant amount of programming.
Thanks for trying out GUAVA! Hope this helps.
