Understanding why YUM seems "slow", and some instant solutions

The previous entry was more of a general explanation about YUM speed and that if used in it's normal environment how current YUM is often more than fast enough, this entry is going to be a companion to it but focus on specific things that might make YUM appear slow but would better be described as using it suboptimally.

Note that I'm still not going to directly compare to other tools as I'm not as familiar with them and, as I said in the previous article, the tools are designed so differently that they don't lend themselves to comparisons. Also, as I also said before, if something is fine if it takes less than 10 seconds if two tools take 6 seconds and 4 seconds it doesn't really matter if yum is the faster (again, see the previous post, this should not be the end goal IMO).
