iOS and macOS Performance Tuning Cocoa, Cocoa Touch, Objective-C, and Swift 英文版本

Sensible Effectivity - Environment friendly ApplyThe goal of  SQL tuning is  the advance of the prevailing execution plan.  The authors talk about the elimination of brakes within the execution plan. Such “brakes” or bottlenecks may be acknowledged by a proper evaluation of the execution plan. For this objective no knowledge mannequin data is required. That is particularly helpful for database directors as a result of they're normally not or insufficiently  aware of the information mannequin. The e book presents quite a few sensible examples with this technique.,解压密码 share.weimo.info

Oracle SQL Tuning with Oracle SQLTXPLAIN: Oracle Database 12c Edition by Stelios Charalambides English | 8 May 2017 | ISBN: 1484224353 | 408 Pages | PDF | 24.39 MB Learn through this practical guide to SQL tuning how Oracle's own experts do it, using a freely downloadable tool called SQLTXPLAIN. This new edition has been expanded to include AWR, Oracle 12c Statistics, interpretation of SQL Monitor reports, Parallel execution, and Exadata-related features. Reading this book and using SQL helps you learn to tune even the most complex SQL, and you'll learn to do it quickly, without the huge learning curve usually associated with tuning as a whole. Firmly based in real-world problems, this book helps you reclaim system resources and avoid the most common bottleneck in overall performance, badly tuned SQL. You'll learn how the optimizer works, how to take advantage of its latest features, and when it's better to turn them off. Best of all, the book is updated to cover the very latest feature set in Oracle Database 12c. Covers AWR report integration Helps with SQL Monitor Report Interpretation Provides a reliable method that is repeatable Shows the very latest tuning features in Oracle Database 12c Enables the building of test cases without affecting production What You Will Learn Identify how and why complex SQL has gone wrong Correctly interpret AWR reports generated via SQLTXPLAIN Collect the best statistics for your environment Know when to invoke built-in tuning facilities Recognize when tuning is not the solution Spot the steps in a SQL statement's execution plan that are critical to performance of that statement Modify your SQL to solve performance problems and increase the speed and throughput of production database systems Who This Book Is For Anyone who deals with SQL and SQL tuning. Both developers and DBAs will benefit from learning how to use the SQLTXPLAIN tool, and from the problem solving methodology in this book.

使用Pytorch进行T5-微调 情感分类 文字摘要

使用C++算法和统计软件构建、测试和调整金融、保险或其他市场交易系统。你已经有了一个想法，做了一些初步的实验，看起来很有希望。你从这里去哪里？好吧，这本书讨论并剖析了这个案例研究方法。 似乎良好的后验性能不足以证明交易真实货币的合理性。您需要对系统的有效性进行严格的统计测试。然后，如果基本的测试确认了你的想法的质量，你就需要调整你的系统，不仅是为了获得最佳的性能，还为了面对不可避免的市场变化时的稳健行为。接下来，您需要量化它的预期未来行为，评估它的实际性能可能有多差，以及您是否能够接受它。最后，你需要找到它的理论性能限制，这样你就知道它的实际交易是否符合这个理论预期，如果它不符合预期，你就可以将系统丢弃。这本书不包含任何可靠的火，有保证的财富交易系统。这些都是一毛不拔的……但是如果你有一个交易系统，这本书将为你提供一套工具，帮助你评估你的系统的潜在价值，调整它以提高盈利能力，并监控它的持续性能，以在它发生灾难性失败之前检测出恶化。任何认真的市场交易者都会很好地采用本书中描述的方法。
