# The practical realities

- ## Modes of operation

  - Multi-threaded Mode - one thread per connection
    - DBI supports threads in perl 5.6 but recent 5.8.x recommended
    - Threads are still not recommended for production use with the DBI
  - Forking Mode - one process per connection
    - Most practical mode for UNIX-like systems
    - Doesn’t scale well to large numbers of connections
    - For is emulated on windows using threads - so see above.
  - Single Connection Mode - only one connection per proxy server process
    - Would need to start many processes to allow many connections
    - Mainly for testing
