It executes in 0 sec when you run it. It might be in the query cache.
Try it with SQL_NO_CACHE. But even then it might run faster than it
did when it got logged in the slow log, because the table's data might
be in memory and therefore faster to access.

Or, perhaps it has an index, but it can't be used in that query.

I have entries in my slow query log for identical queries but, as you can see

2. show slave status
