Point <code>[server] sites_dir</code> at a directory and every <code>Host</code> maps to its own docroot and its own Turso database file. One process serves all of them. The first question anybody asks about that is &ldquo;how many sites fit on a box?&rdquo; The honest way to answer it is to turn the question around. What does <strong>one more</strong> site cost? If you know the marginal RAM, file descriptors, CPU and disk for a tenant, the box size falls out of arithmetic.</p>
