very often thwarted by the amount of
Personal Review: Analyzing Computer Systems Performance:
With Perl: PDQ by Neil J. Gunther
The coverage of the theory in the first part of the book is very well done.
However, its the practical examples in the second half where the book
really shines. There are a number of examples modeling client server and
web applications.

A copy of his modeling tool, PDQ, is available by download from his
website. This version is in Perl. Even though I am not a very experienced
Perl programmer I think this is an interesting way to get more practice by
building PDQ models. The PDQ package is explained very well and a
number of example models are covered.
Some of the examples are from various scattered publications. It's great to
get these example models collected in one volume. Dr. Gunthers
characteristic sense of humor comes through in the examples.
There is some very practical information about model validation and what
to do to account for hidden latencies. There are clear examples of how to
practice the art of applying queuing models to real problems.
I would have liked to see some more examples of load dependent servers.
Overall I rate the book five stars and I really appreciate getting the
modeling software for free!
