  // We maintain a persistent cache of hook implementations in addition to the
  // static cache to avoid looping through every module and every hook on each
  // request. Benchmarks show that the benefit of this caching outweighs the
  // additional database hit even when using the default database caching
  // backend and only a small number of modules are enabled. The cost of the
  // $this->bootstrapCache->get() is more or less constant and reduced further when
  // non-database caching backends are used, so there will be more significant
  // gains when a large number of modules are installed or hooks invoked, since
  // this can quickly lead to module_hook() being called several thousand times
  // per request.
