About O/ρ

O/ρ is a reference to two quantities in IT performance engineering:

  • Big-O notation is used to describe time complexity of algorithms - how algorithm execution time scales with the volume of the input.
  • \( \rho \) is defined to be the utilization of queuing systems.

Inadequate or lack of attention for scalability and utilization is a common cause for failing IT projects. Scalability matters - perhaps the mother of all functionality, as something that does not respond or cannot complete in time, really has no functionality at all.
