This is the default, if you make this bigger yum won't see if the metadata
is newer on the remote and so you'll "gain" the bandwidth of not having to
download the new metadata and "pay" for it by yum not having correct
information.
It is esp. important, to have correct metadata, for distributions like
Fedora which don't keep old packages around. If you don't like this checking
interupting your command line usage, it's much better to have something
manually check the metadata once an hour (yum-updatesd will do this).
