Hi, I have noticed that the dependency resolution stage of yum can be painfully slow. To give an example, I am running yum 2.0.4 on redhat 9 and "yum install xine" has been at that stage for several minutes now with the CPU at near 100 percent utilisation. It seems to me, perhaps naively, that using the correct data structure and caching this should take no more than a second or two. As a result I would like to offer to help redesign the algorithm used. So what I really need is some technical information about what is required and who I should be in touch with. Kind regards, Raphael
