<p dir="auto">When these limits were set in 2008 (<a class="commit-link" data-hovercard-type="commit" data-hovercard-url="https://github.com/openstreetmap/mod_tile/commit/a16d3b730fec57591c2a648c2bf46215cec308f3/hovercard" href="https://github.com/openstreetmap/mod_tile/commit/a16d3b730fec57591c2a648c2bf46215cec308f3"><tt>a16d3b7</tt></a>) it would take a few minutes to clear through the dirty tile queue, giving it the ability to even out load over a few minute timescale, and let the work in the queue be done when the server is no longer busy. These days, a server can clear through 1000 metatiles in seconds, meaning the queue fills up nearly instantly and starts dropping tiles.</p>
<p dir="auto">Increasing these limits by 8x attempts to restore some of the old utility of the queue.</p>
<p dir="auto">By my estimates, in 2008 a server might have been doing 5 metatiles/second, while now it's 100 metatiles/second.</p>
<p dir="auto">If we were starting over, I wouldn't consider the gains of having the queue worth the additional code complexity.</p>
