Performance comprehension of production software

在加拿大和美国，软件开发人员都是薪酬最高、最受欢迎的人才之一；仅加拿大就面临着18.2万名ICT员工的缺口。随着生产率的提高，短缺至少可以得到部分缓解。我们的项目将解决软件开发生产力中一个重要且经常被忽视的方面：性能调试和调优。最近的一项调查显示，92%的开发人员在前一年面临影响客户的性能问题；总而言之，约300名受访工程师花了130个人月的时间诊断和修复性能问题。受访者进一步承认，性能调整最困难的部分实际上并不是修复问题，而是收集和分析证据并找到其根本原因。

Software developers are among the most highly paid and sought-after talent in both Canada and the US; Canada alone facing a gap of 182,000 ICT workers. Shortage can be at least partially relieved with improved productivity. Our project will address an important and often overlooked aspect of software development productivity: performance debuggingtuning. A recent survey revealed that 92% of developers faced customer-affecting performance issues during the preceding year; all in all, ~300 interviewed engineers spent 130 man-months diagnosing and fixing performance problems. The respondents further admitted that the most difficult part of performance tuning was not actually fixing the problem, but gathering and analyzing evidence and getting to its root cause.
