dccd tune-up

Hi,
I several times tried --with-db-memory=X and --enable-big-db configuration
parameters and I couldn't see any difference in the dccd performance.
Is there any reason to change them and when? And my main problem are RTTs,
I still getting high RTTs and I can't understand why? BTW, all my servers
are FreeBSD.
Thanks,
Val
