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182,000名信息通信技术工作者的缺口。生产力的提高至少可以部分缓解短缺。我们的项目将解决软件开发生产力的一个重要且经常被忽视的方面：性能调试调优。最近的一项调查显示，92%的开发人员在过去一年中遇到了影响客户的性能问题；总而言之，约300名接受采访的工程师花了130个月的时间诊断和修复性能问题。受访者进一步承认，性能调优中最困难的部分并不是解决问题，而是收集和分析证据，找到问题的根本原因。

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.
