<p dir="auto">Hi Team, Thanks for the great work you are doing. I'm completely new to ruby and to this project.</p>
<p dir="auto">I'm currently running a local version of osm-website, and I'm calling this endpoint:</p>
<pre class="notranslate"><code class="notranslate">https://myLocalWebsite/api/0.6/map?bbox=46.699791,24.6334425,46.7233944,24.6471732
</code></pre>
<p dir="auto">but it's taking too long in the rendering phase, I see the following line in logs:</p>
<pre class="notranslate"><code class="notranslate">Completed  200 OK  in 25244ms (Views: 19820.2ms | ActiveRecord: 4122.8ms (26457 queries, 24031 cached) | GC: 1631.1ms)
</code></pre>
<p dir="auto">I see a lot of queries like this:</p>
<pre class="notranslate"><code class="notranslate">SELECT "changesets".* FROM "changesets" WHERE "changesets"."id" = $1 LIMIT $2
</code></pre>
<p dir="auto">So I have updated maps_controller to include changeset with nodes <a href="https://github.com/openstreetmap/openstreetmap-website/blob/master/app/controllers/api/maps_controller.rb#L31">here</a>, instead of loading it while rendering. it improved the performance but it's still taking around 11-12 seconds.</p>
<p dir="auto">When I'm trying the same request on the public website, it's taking less than 1 second (even without my change)</p>
<pre class="notranslate"><code class="notranslate">https://api.openstreetmap.org/api/0.6/map?bbox=46.699791,24.6334425,46.7233944,24.6471732
</code></pre>
<p dir="auto">So I'm wondering if there is any type of caching or multi-threading happening on the public website but not happening on my version.</p>
<p dir="auto">Thanks in advance,</p>
