  • Optimizing web servers for high throughput and low latency

    This is an expanded version of my talk at NginxConf 2017 on September 6, 2017. As an SRE on the Dropbox Traffic Team, I’m responsible for our Edge network: its reliability, performance, and efficiency. The Dropbox edge network is an nginx-based proxy tier designed to handle both latency-sensitive metadata transactions and high-throughput data transfers. In a system that is handling tens of gigabits per second while simultaneously processing tens of thousands latency-sensitive transactions, there are efficiency/performance optimizations throughout the proxy stack, from drivers and interrupts, through TCP/IP and kernel, to library, and application level tunings.

  • Squeezing More Juice Out Of Gentoo With Graphite, LTO Optimizations

    Developer Shane Peelar has come up with a Gentoo Portage configuration for building out the distribution with aggressive compiler optimizations in the name of performance.

    Peelar's Gentoo configuration will build with -O3 optimizations, GCC Graphite optimizations, and LTO (Link Time Optimizations).

  • Debian-Administration.org is closing down

    The site will go read-only at the end of the month, and will slowly be stripped back from that point towards the end of the year - leaving only a static copy of the articles, and content.

  • What you need to know to manage Linux disks

    There are numerous other commands for examining disks and file systems. Those described here are some of the most useful and informative. Using them periodically has advantages as the easiest way to spot problems is becoming so used to the output of commands such as these that you easily spot the kind of differences that might indicate problems.

  • Open education: How students save money by creating open textbooks
    Most people consider a college education the key to future success, but for many students, the cost is insurmountable. The growing open educational resource (OER) movement is attempting to address this problem by providing a high-quality, low-cost alternative to traditional textbooks, while at the same time empowering students and educators in innovative ways. One of the leaders in this movement is Robin DeRosa, a professor at Plymouth State University in New Hampshire. I have been enthusiastically following her posts on Twitter and invited her to share her passion for open education with our readers. I am delighted to share our discussion with you.

Linux 4.10 To Linux 4.15 Kernel Benchmarks

The ThinkPad X1 Carbon has been enjoying its time on Linux 4.15. In addition to the recent boot time tests and kernel power comparison, here are some raw performance benchmarks looking at the speed from Linux 4.10 through Linux 4.15 Git. With this Broadwell-era Core i7 5600U laptop with 8GB RAM, HD Graphics, and 128GB SATA 3.0 SSD with Ubuntu 17.10 x86_64, the Linux 4.10 through 4.15 Git mainline kernels were benchmarked. Each one was tested "out of the box" and the kernel builds were obtained from the Ubuntu Mainline Kernel archive. Read more
