All Subscriptions took 130-170 ms when used a minute before, and 0.5-1.9 s
the first time after a quiet spell. Its sort needs each item's date, which
was only in the item's row, so every one of a person's 13,700 rows was
read, show notes inline and all, and cold that came off disk; count_in,
which needs no date, took 20 ms throughout. entries_by_time holds the keys
and dates, the page's keys are sorted and cut from it, and only the rows
shown are read. On a copy of the shape in the test database: 619 pages
read against 4,174, with no visit to the table. Neither change alone
helped.
