From the reviews
"The literature of computer performance analysis is generally composed of two groups: heavy theoretical treatises and performance cookbooks. [...] Surprisingly, this book is exceptionally well balanced between theory and practice [...] . I strongly recommend this book, both for the novice practitioner and for the experienced performance analyst. Both can extract a vast array of benefits, ranging from understanding the theoretical concepts of performance modeling, to building for themselves a powerful modeling tool [...] ."

From the reviews of the second edition:
“Besides its case studies on applying queueing theory to the analysis of computer performance, this book on queueing circuits also includes a quick user guide to Perl Pretty Damn Quick (PDQ), a reference manual, and numerous examples. ... The book is written to be a field manual for enlightened practitioners of performance analysis, or possibly a school textbook. ... It is a laudable achievement to make performance analysis theoretical foundations available to anyone who is interested and can master high-school algebra.” (A. Squassabia, ACM Computing Reviews, December, 2011)
