I'm setting up the permalink for my website and while reading in the wordpress codex at this address, http://codex.wordpress.org/Using_Permalinks
it appears that using just the postname is bad.
A sanitized version of the title of the post (post slug field on Edit Post/Page panel). So “This Is A Great Post!” becomes this-is-a-great-post in the URI (see Using only %postname%). Starting Permalinks with %postname% is strongly not recommended for performance reasons.
It puts a load on the server because it takes longer to find the article in the database. From research, I am getting conflicting information on whether this is still in issue or not. It's strange because most WP sites seem to use this format. Most recents articles I find from a year ago still seem to conflict. Can anyone shed some light on this and whether I should be concerned.
If I don't got with the %postname% I will probably add the post ID in front but I would rather go with just the post name.
