<p><a class="user-mention" data-hovercard-type="user" data-hovercard-url="/users/joto/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/joto">@joto</a>, another question regarding this: is the 30% performance hit you report only for true osm2pgsql guided <strong>updates</strong>, so this performance hit is not relevant to users who do not to do updates but instead a full re-import to update their database?</p>
<p>If so, I would argue that it is more likely that novice users are in the second group, only doing full re-imports. Setting up osm2pgsql to do updates is likely the "advanced" option.</p>
<p>If that is the case, this option may actually be desirable for novice users, as it would reduce temporary disk space usage at no to little cost, and a slightly more user-friendly name an option.</p>
<p>Of course, if ordinary imports are affected as well with a 30% performance hit, than I agree this is more of an "advanced" option that should likely not be default.</p>
