A. If both are guaranteed to exist then A is better. If both maxout without finding anything, then you ask the same number of nodes ether way. If the data is close to you, it only has to go through the number of nodes between you and it ether way. So having a high htl is only more stressful to the network if the data is a long way off. However the data is further away than maxHtl/2 then it is fairly likly that the other file is too. Consider that ideally the best HTL nodes out of m^HTL get asked. Where m is the average number of unique outgoing connections per hop. The ideal solution would be to select to ether get file A or B baised on which is closest to your specialization, or you think you can get the fastest. _______________________________________________ Devl mailing list [EMAIL PROTECTED] http://dodo.freenetproject.org/cgi-bin/mailman/listinfo/devl
