11423	user_nicename should get memcached	Denis-de-Bernardy		"When displaying an author's page, there are queries:

{{{
SELECT ID FROM users WHERE user_nicename='whoever'

SELECT display_name FROM users WHERE user_nicename = 'whoever'
}}}

the second one could be avoided with a non-persistent cache bucket indexed on user_nicename. we could store the user_id, for instance.

both of them could be avoided with the same bucket if the latter is made persistent."	enhancement	closed	normal	3.1	Optimization	2.9	normal	fixed	has-patch
