This blog forms part of the http://performanceGuru.com website which focuses on performance tuning UNIX-like Operating Systems (including Linux).
Added PDQ to the tools page of my website
. PDQ is covered in Neil Gunther's book "The Practical Performance Analyst"
, which is an excellent text covering Erlang's
concept of queuing theory and its practical uses in capacity planning and performance tuning. The description on my site is as follows:
PDQ (Pretty Damn Quick) is a queuing model solver, not a simulator. The queuing theory models discussed in Chapters 2 and 3 of The Practical Performance Analyst are incorporated into the solution methods used by PDQ. This saves you the labour of implementing this code each times you construct a queuing model and allows you to concentrate on the accuracy of your model rather than the accuracy of the solutions.
