How long does it takes for keywords to appear in Webmaster Tools?

Hello guys
I noticed that when i add a new post to my blog, the keywords related to the post takes lot of time to appear in Google Webmaster Tools knowing that the post is indexed by Google after couple of days from publishing it.

Is there a way to speed the process?
how long usually as an average it takes for keywords related to a new post to appear in Webmaster Tools?
Thanks a lot
