Software Performance and Scalability: A Quantitative Approach
Henry H. Liu
Praise from the Reviewers:
"The practicality of the topic in a real-world scenario distinguishes this ebook from others on hand at the market."
—Professor Behrouz Far, college of Calgary
"This publication might exchange the pc association texts now in use that each CS and CpE pupil needs to take. . . . it really is a lot wanted, good written, and thoughtful."
—Professor Larry Bernstein, Stevens Institute of Technology
A particular, academic textual content onsoftware functionality and scalability
This is the 1st e-book to take a quantitative method of the topic of software program functionality and scalability. It brings jointly 3 distinct views to illustrate how your items will be optimized and tuned for the absolute best functionality and scalability:
The Basics—introduces the pc and software program architectures that predetermine the functionality and scalability of a software program product in addition to the foundations of measuring the functionality and scalability of a software program product
Queuing Theory—helps you examine the functionality legislation and queuing types for examining the underlying physics in the back of software program functionality and scalability, supplemented with ready-to-apply strategies for making improvements to the functionality and scalability of a software program system
API Profiling—shows you the way to layout extra effective algorithms and attain optimized functionality and scalability, aided by way of adopting an API profiling framework (perfBasic) equipped at the thought of a functionality map for drilling down functionality root factors on the API level
Software functionality and Scalability can provide a really expert ability set that may assist you to layout and construct functionality into your items with rapid, measurable advancements. Complemented with real-world case reviews, it's an fundamental source for software program builders, caliber and function coverage engineers, architects, and executives. it really is anideal textual content for college classes relating to computing device and software program functionality overview and will even be used to complement a path in desktop association or in queuing conception for upper-division and graduate laptop technological know-how students.

receive, yet considering talents are not easy to procure inside of a brief time period. you must imagine consistently how one can increase your productiveness and efﬁciency via doing issues in additional efﬁcient methods. As you retain considering and practising, you’ll steadily develop into a completely ﬂedged software program functionality engineer who can clear up software program functionality difficulties in a question of hours whereas others could spend weeks or maybe months with out good fortune. furthermore, a rigorous strategy is important in your software program.
for selecting right for software program functionality and scalability exams is that it's going to be with regards to what the client will use in creation, or not less than even more strong than the platforms used for improvement and QA assessments. do not forget that the functionality and scalability of a software program approach strongly depend upon the used for trying out, and for this reason don't choose undersized simply because it’s to be had. in case your software program is firm classification software program, it doesn’t make experience to run.
