You boot Laravel or Symfony once, keep the container in memory, and serve thousands of requests out of the same process. <a href="https://github.com/ephpm/ephpm">ePHPm</a> has had a worker mode for a while. Like most worker runtimes it had a quiet hole in it. You couldn&rsquo;t step debug a request with Xdebug. I wanted that fixed without patching Xdebug and without giving up the warm pool. The answer ended up being to stop fighting the constraint and route around it. The debug lane is merged on main and coming in the upcoming v0.12.0 release.</p>
