### Concurrence et Burgers { #concurrency-and-burgers }

L'idée de code **asynchrone** décrite ci-dessus est parfois aussi appelée **« concurrence »**. Ce qui est différent du **« parallélisme »**.

     * file attributes such as ACLs but it does copy regular attributes as
     * well as create and last write times. This method is almost twice as
     * efficient as manually copying as it employs an additional write
     * thread to read and write data concurrently.
     * <br>
     * It is not possible (nor meaningful) to copy entire workgroups or
     * servers.

   * segments, each governed by its own write lock. The segment lock is taken once for each explicit
   * write, and twice for each cache loading computation (once prior to loading the new value, and
   * once after loading completes). Much internal cache management is performed at the segment
   * granularity. For example, access queues and write queues are kept per segment when they are
