In 1974, Donald Knuth wrote, "We should still ignore small efficiencies, say approximately ninety seven% of the time: untimely optimization is the foundation of all evil." With desktops to be had now which are hundreds of thousands of occasions speedier than these on hand then, cutting-edge programmers have even much less cause to fret approximately shaving cycles and saving bytes than these a new release in the past. yet "less" isn't really "none": each infrequently, squeezing the final ounce of functionality out of the computer fairly does topic. This ebook is written through over a dozen builders who've grappled with gradual code, reminiscence leaks, or uncontrollable latency in open resource software program. They percentage their error and successes, and provides the reader an over-the-shoulder view of ways they approached their particular demanding situations. With examples from bioinformatics study code to internet browsers, the ideas are as diversified because the difficulties. This publication can assist junior and senior builders alike know the way their colleagues take into consideration functionality.

Robert Warnke, Thomas Ritzau's QEMU PDF
Dieses Fachbuch beschreibt die software program QEMU. Das kostenlose, quelloffene QEMU emuliert die komplette eines pcs mit CPU. Damit ist es möglich, software program verschiedener Prozessorarchitekturen auszuführen. QEMU ist nicht, wie zum Beispiel VMware, auf die x86-Architektur beschränkt. Zum QEMU-Paket gehört auch das leistungsfähige software qemu-img zum Anlegen, Konvertieren und Verschlüsseln von Image-Dateien (virtuellen Festplatten) in unterschiedlichen Formaten, auch anderer Virtualisierungssoftware.

Michael Snoyman (Warp): Michael is the lead software engineer at FP Complete. He is the founder and lead developer of the Yesod Web Framework, which provides a means of creating robust, high-performance web applications. His formal studies include actuarial science, and he has previously worked in the US auto and homeowner insurance industry analyzing large data sets. Kazu Yamamoto (Warp): Kazu is a senior researcher of IIJ Innovation Institute. He has been working for open source software around 20 years.
Each chapter is written by real developers who have had to make an existing system faster or who had to design something to be fast in the first place. They cover many different kinds of software and performance goals; what they have in common is a detailed understanding of what actually happens when, and how the different parts of large applications fit together. Our hope is that this book will—like its predecessor The Architecture of Open Source Applications—help you become a better developer by letting you look over these experts’ shoulders.
In other words, there are a lot of variables at play, but it is not unusual for a DNS lookup to take up to several hundred milliseconds. Ouch. 2 - Three-way handshake With the resolved IP address in hand, Chrome can now open a new TCP connection to the destination, which means that we must perform the “three-way handshake”: SYN > SYN-ACK > ACK. This exchange adds a full round-trip of latency delay to each and every new TCP connection—no shortcuts. Depending on the distance between the client and the server, as well as the chosen routing path, this can yield from tens to hundreds, or even thousands, of milliseconds of delay.
