<p>Also I found that there is a little inconsistent information about --slim mode and required cache size.</p>
<p>In <a href="https://osm2pgsql.org/doc/manual.html#caching" rel="nofollow">8.3 Caching</a> section:</p>
<pre><code> The rule of thumb in slim mode is as follows: use the size of the PBF file you are trying to import or about 75% of RAM, whatever is smaller.
</code></pre>
<p>In <a href="https://osm2pgsql.org/doc/manual.html#middle-command-line-options" rel="nofollow">8.5 Middle Command Line Options</a> section:</p>
<pre><code> As a rule of thumb, give a bit more than the size of the import file in PBF format.
</code></pre>
