The thing is that there is no longer a "standard fee" you can set or remember and always get a quick confirmation. Thats the reason newer versions of bitcoin core come with an algorithm to estimate a good fee for the current[1] state of the network. If you do not want to update for some reason at least check with pages like
https://bitcoinfees.21.co/[1] obviously this isnt entirely true, as the data will always be slightly outdated
I stumpled already over this URL
https://bitcoinfees.21.co/ when I googled for infos on tuesday in the internet (and still wonder what its heading "since 1759" means).
Do you know a URL where I can watch the current size (say in MB) of total unconfirmed transactions waiting for inclusion into the blockchain (and perhaps their number)?
