It&rsquo;s the machine on my desk with 32 threads and 62 GB of RAM. Everybody who does that learns the first rule early: don&rsquo;t put your data on <code>/mnt/c</code>. DrvFs is the 9p-backed mount that exposes the Windows drives inside WSL, and it&rsquo;s slow for file-heavy work. So the databases, the docroot and the build output all live on the WSL ext4 disk. My scaling harness for <a href="https://github.com/ephpm/ephpm">ePHPm</a> even says so in capital letters in its README.</p>
