Performance profile

How much work a call to WP_Session_Tokens::get_session() does, and what it touches: the algorithmic scaling, the Zend instruction count per call across PHP versions, the hooks it hands control to, and the core code that calls it. Measured from the compiled opcodes, not a stopwatch, so every number is identical on any machine running the same PHP version, and every function in core is ranked by cost.

Cost class

Trivial

Touches nothing outside its own arguments.

Scaling

Constant

No loop in the body: the same number of instructions runs whatever you pass in.

Plugin surface

None

Nothing here hands control to plugin code.

Called by

3

3 places in core call this, so the cost is paid more often than your own code shows.
