hi,
i was looking at memory usage on zedler recently, and discovered that grant
tables are using a significant amount of memory. i have implemented a
better solution, but as a side-effect, names of databases are changing.
from now on, each database X should be accessed as X_p (e.g.: "enwiki_p").
the old names will stop working shortly (sooner rather than later, since i
would like to reclaim the wasted memory).
also, the "rc_filtered" and "ar_filtered" tables will be known as
"recentchanges" and "archive" instead.
this will free about 2GB of RAM to be used by InnoDB, which should improve
performance.
