軟體簡介:
　
Code efficiency. There are other words we can use (optimization, performance,
speed), but it's all about making existing code run faster. Whether for desktop,
mobile, or web apps, in this course you'll see how to identify pain points and
measure them accurately, as well as view multiple approaches to improve the
performance. Author Simon Allardice covers everything from "quick fixes" to
more complex (but more accurate) algorithms.

Learn to choose the right data types, understand the pitfalls of using
high-level languages, and decide where to spend your time. Plus, see how the
underlying memory management model may have more of an impact than you
realize, and what performance issues you can expect working with databases and
web services.
