Foreword by .NET Remoting guru Ingo Rammer BACK IN 1999, the ACM published a study that presented a comparison of 40 independent implementations of a computationally intensive problem, created by different programmers in either Java the then-current managed runtime environmentor C/C++. It concluded with the finding that interpersonal differences between the developers "are much larger than the average difference between Java and C/C++" and that "performance ratios of a factor of 30 or more are not uncommon between the median programs from the upper half versus the lower half." This should teach you something: If you are not a guru-level C++ programmer, then the chance is quite high that a managed code implementation performs as well as the average C++ solution, especially given the fact that most .NET languages simply allow you fewer possibilities to introduce subtle memory related or performance-related issues. And keep in mind that this study was conducted several years ago, and that Just-In-Time Compilation (JIT) as well as memory management and garbage collection (GC) technologies have been improved in the meantime! This, however, doesn't mean that you can't create horribly slow, memory-eating applications with .NET. That's why you should be really concerned about the other part of the study's conclusion, namely that "interpersonal differences . . . are much larger." In essence, this means that you have to know about how to optimize your applications so that they run with the expected performance in a managed environment. Even though .NET frees you from a lot of tasks that in C++ would have been your responsibility as a developer, these tasks still exist; these "little puppets" have only cleared the main stage and now live in some little corner behind the scenes. If you want your application to run in the top performance range, you will still need to find the right strings to pull to move these hidden figures and to basically keep them out of the way of negatively affecting your application's performance. (Lutz Prechtelt, "Comparing Java vs. C/C++ Efficiency Differences to Interpersonal Differences," Communications of the ACM 42, no. 10 [October 1999]: 109–112.) But knowing about the common language runtime's internals is still not enough, as lots of performance issues actually turn up during application design and not just during the coding stage. Collections, remoting, interoperability with unmanaged code, and COM components are not the only things that come to my mind in this regard. It is the aim of Nick's book to enable you to understand the design issues as well as the underlying CLR mechanisms in order to create the programs that run on the better side of the 30-times performance difference quoted in the ACM study. Nick really managed to create a book that addresses these issues, which will otherwise turn up when carelessly coding to a managed environment. This book will allow you to get into the details without being overwhelmed by the underlying complexity of the common language runtime. The only thing you have to resist after reading the book is the urge to over-optimize your code. I was delighted to see that Nick begins with a discussion of identifying an application's performance-critical sections and only later turns towards isolating and resolving these real performance bottlenecks. This is, in my opinion, one of the most important tasks—and also one of the most complex ones—when working with large-scale applications. And now, read on, and enjoy the ride to the better side of a 30-fold performance difference. Ingo Rammer, author of Advanced .NET Remoting Vienna, Austria http://www.ingorammer.com About the Book Maximizing .NET Performance is the first book dedicated entirely to providing developers and architects with information on .NET Framework performance. .NET is a technology with a vast surface area, and coverage of every aspect of performance relevant to all .NET technologies is not possible within a single volume. This book concentrates on the performance of .NET Framework technologies like garbage collection, .NET Remoting, and Code Access Security. Because these technologies form the building blocks upon which all .NET applications run, the information in this book is relevant to all .NET developers. In addition to providing high-level material on achieving software with good performance characteristics, the books aims to enhance your knowledge of the design and implementation of the framework, and to provide the tools and techniques to allow you to conduct your own investigation into performance problems. Rather than taking a "tips and tricks" approach, the book aims to provide a detailed exploration of each topic and explore the "why" and "by how much" aspects of performance that are often overlooked.

Elevate your game in the face of challenging market conditions with this eye-opening guide to portfolio management Investing Amid Low Expected Returns: Making the Most When Markets Offer the Least provides an evidence-based blueprint for successful investing when decades of market tailwinds are turning into headwinds. For a generation, falling yields and soaring asset prices have boosted realized returns. However, this past windfall leaves retirement savers and investors now facing the prospect of record-low future expected returns. Emphasizing this pressing challenge, the book highlights the role that timeless investment practices – discipline, humility, and patience – will play in enabling investment success. It then assesses current investor practices and the body of empirical evidence to illuminate the building blocks for improving long-run returns in today’s environment and beyond. It concludes by reviewing how to put them together through effective portfolio construction, risk management, and cost control practices. In this book, readers will also find: The common investor responses so far to the low expected return challenge Extensive empirical evidence on the critical ingredients of an effective portfolio: major asset class premia, illiquidity premia, style premia, and alpha Discussions of the pros and cons of illiquid investments, factor investing, ESG investing, risk mitigation strategies, and market timing Coverage of the whole top-down investment process – throughout the book endorsing humility in tactical forecasting and boldness in diversification Ideal for institutional and active individual investors, Investing Amid Low Expected Returns is a timeless resource that enables investing with serenity even in harsher financial conditions.

Effective allocation and utilization of resources are fundamental to achieving optimal public health outcomes. Health economics provides valuable insights into how financial resources are allocated across different healthcare sectors and their subsequent effects on health indicators and health-related quality of life. By conducting in-depth reviews of existing research and policy evaluations on public health expenditure and their performance, this Research Topic aims to shed light on best practices, challenges, and innovative approaches to optimize public health expenditure for maximum impact. Potential topics for review articles may include, but are not limited to: • Review of health economic evaluation methods applied to public health interventions, including cost-effectiveness, cost-benefit, cost-utility analyses, and budget impacts. • Assessment of the relationship between public health expenditure and health outcomes, including the impact on disease prevention, healthcare access, and quality of life. • Evaluation of health financing systems and their influence on healthcare equity and affordability, with a focus on vulnerable and marginalized populations. • Analysis of the role of public-private partnerships in healthcare funding and service delivery to enhance overall health system performance. • Review of healthcare budget allocation strategies and their implications for resource allocation in different public health domains. • Exploration of innovative financing mechanisms, such as social impact bonds and health insurance schemes, to improve healthcare accessibility and efficiency. • Critique of policy interventions aimed at optimizing public health expenditure and enhancing performance in healthcare service delivery.
