If my understanding is correct, the yum in rawhide builds a sqlite database when needed and then queries the database instead of trying to reload all the information into memory with every yum operation. With the rawhide version of yum, multiple runs of yum where the information on the mirrors is unchanging results in much quicker response thanks to the local sqlite database. The sqlite database is only rebuilt if yum detects a change in the metadata at the contacted mirror. Though you can still speed up things even further for some operations like list and info where you don't need to contact a mirror to download any packages. yum makecache (freshen the local cache of all the metadata) yum -C list yum -C info but if you dont have the packages and the headers downloaded locally to the cache yum -C install isn't going to work, so it might not be as useful to you as the other 2 commands. If you have to go out and touch the network... that means examining the metadata at the mirror and potentially rebuilding the local database of information. -jef
