to use Tornado’s web framework and HTTP server together. Asynchronous and non-Blocking I/O Real-time web features require a long-lived mostly-idle connection per user. In a traditional synchronous web code should aim to be asynchronous and non-blocking because only one operation can be active at a time. The terms asynchronous and non-blocking are closely related and are often used interchangeably, like bcrypt [http://bcrypt.sourceforge.net/], which by design use hundreds of milliseconds of CPU time, far more than a typical network or disk access).

In a traditional synchronous web code should aim to be asynchronous and non-blocking because only one operation can be active at a time. The terms asynchronous and non-blocking are closely related and are often used interchangeably, consider password hashing functions like bcrypt, which by design use hundreds of milliseconds of CPU time, far more than a typical network or disk access).
