Hi Peter,
The ~2900 tiles at prio 25 are the bulk rendering of the z0-6 tiles that is started each 1. of a month.
And 10 days later, they are still in the queue.. The last five days, the dirty-queue nearly reached 0, but it looks like the queue stabilised at a daily max of 7k.
Are there any plans for optimising? Perhaps some indexes on often used tags in hstore? Or another rendering strategy (like Kay suggested [i.e. always use 10% for 'background'])?
(I am no expert on this, so I don't know what would help most..)
Regards, Thomas
