Slow startup #9

Open GrimPixel opened 2 years ago

Anki normally starts within 2 seconds, With this add-on, it takes an extra 13 seconds. Is it possible to accelerate it?

Most of the time is in the database queries.

Only enabling the limits you care about will help. There are per-deck limits and total limits. If you disable the per-deck limits, that will probably help, assuming your needs are met by the total limits alone. If per-deck limits are enabled, there are database queries for each deck.

Rather than a query per deck, it would probably be possible to consolidate the queries to a single query that returned the results required for all decks in a single query. This might be quicker overall and probably not too much more complicated to implement.

Caching query results would help, though not much with startup.

I haven't used Anki for about a year now, so I don't know how the current version behaves. The scheduler and overall implementation were evolving rapidly when I was last using it. As I don't use Anki, I'm not very motivated to do more work on this add-on myself, but feel free try profiling and improving the database queries if you like.
