I live in a country like India and internet is really slow

So I would like yum to not download metadata and other unneccesary data everytime.

I have seen that downloading the updates and fedora repository metadata takes a lot of time.

So can I configure way to stop it or make yum start the download process faster?

(I already use the fastestmirror plugin and download speed is proper (as per my internet connection))

Yum Fast Downloader plugin it's awesome. It works and now yum it's fast enough. Hmm, I think this comment should be converted to an answer.

Yes. You can either reconfigure yum to cache the metadata for a longer period using metadata_expire (refer to man page of yum.conf) or use dnf which caches for a longer period by default.

metadata would mean information about package version of a remote repository. Between two metadata refresh the package version in the current metadata would be the latest even if upstream has released a new package and that is available in the repository. Am I correct?

What are the recommended value for metadata_expire?

What are the repercussions of longer expire timeout?

How can I manually refresh metadata?

You are correct. Yum default is 6 hours while you can even configure it to be 2 days. It just means you won't necessarily get the very latest updates. yum clean expire-cache will force expire the cache.
