Hello, in my mybb database are tables:

"mybb_rememberus_log" it has 60,141 entries and 1.9Mb
"mybb_posts" it has 10,056 entries and 4.9Mb
"mybb_captcha" it has 7,322 entries and 1Mb

i want to ask what is that rememberus log table for?

also many times i found queries into "mybb_sessions" table are slow and are visible in current mysql queries list often. i have many databases but this query is there many times

The table mybb_rememberus_log is not part of a default installation. What I believe it would be responsible for is which users are always logged in ( they checked the remember me option ).

The mybb_sessions table stores information about a session such as a users current location, ipaddress, userid, and last activity. If it gets really large, you can truncate it and no damage is done. All that will be affected is how many users it says are online. The next time they go to a page it will count them in the online list again.
