    <dc:creator>mlednor</dc:creator><description><![CDATA[HAProxy, which stands for High Availability Proxy, is a popular open source software TCP/HTTP Load Balancer and proxying solution which can be run on Linux, Solaris, and FreeBSD. Its most common use is to improve the performance and reliability of a server environment by distributing the workload across multiple servers (e.g. web, application, database). It is used in many high-profile environments, including: GitHub, Imgur, Instagram, and Twitter.

In this tutorial, we will go over how to use HAProxy for SSL termination, for traffic encryption, and for load balancing your web servers. We will also show you how to use HAProxy to redirect HTTP traffic to HTTPS.

Native SSL support was implemented in HAProxy 1.5.x, which was released as a stable version in June 2014.]]></description>

Load balancing can improve the performance, availability, and resilience of your environment.

Layer 7 reverse proxying and load balancing is suitable for your site if you want to have a single domain name that serves multiple applications, as the http requests can be analyzed to decide which application should receive the traffic.

This tutorial is written with WordPress and a static web site as examples, but its general concepts can be used with other applications to a similar effect.]]></description>

    <dc:creator>mlednor</dc:creator><description><![CDATA[In this tutorial, we will teach you how to use HAProxy as a layer 4 load balancer for your WordPress servers--specifically the web application tier. Load balancing the application servers adds redundancy to your setup, which increases reliability in case of server failures or networking issues, and spreads the load across multiple servers for increased read performance. We are assuming that your setup includes a WordPress application server that connects to a separate MySQL database server (see the prerequisites for a tutorial on how to set that up).

Layer 4 load balancing is suitable for your site if you are only running a single web server application. If your environment is more complex (e.g. you want to run WordPress and a static web server on separate servers, with a single entry point), you will need to look into Application Layer (Layer 7) load balancing.]]></description>

If you are currently hosting your web server and database backend on the same VPS, a good idea may be to separate these two functions so that each can operate and grow on its own machine.

In this guide, we'll discuss how to configure a remote database server that your web server can connect to for dynamic content. We will be using WordPress as an example so that we have something to work with. We'll configure Nginx on our web server and then connect it to a MySQL database on a remote machine. We'll be doing all of this on an Ubuntu 12.04 VPS instance for our demo.]]></description>

However, in most cases at least some small savings can be achieved through image recompression and CSS minification. If the savings calculated by the test pilot aren't that huge, it's either because there's not much to save about your site (e.g. images are too small for downscaling and you don't use media queries), or because you just did a pretty good job already!]]></description>

    <dc:creator>mlednor</dc:creator><description><![CDATA[In previous posts on vm.swappiness and using RAM disks we talked about how the memory on a Linux guest is used for the OS itself (the kernel, buffers, etc.), applications, and also for file cache. File caching is an important performance improvement, and read caching is a clear win in most cases, balanced against applications using the RAM directly. Write caching is trickier. The Linux kernel stages disk writes into cache, and over time asynchronously flushes them to disk. This has a nice effect of speeding disk I/O but it is risky. When data isn’t written to disk there is an increased chance of losing it.]]></description>

    <dc:creator>mlednor</dc:creator><description><![CDATA[dummynet is a live network emulation tool, originally designed for testing networking protocols, and since then used for a variety of applications including bandwidth management. It simulates/enforces queue and bandwidth limitations, delays, packet losses, and multipath effects. It also implements various scheduling algorithms. dummynet can be used on the machine running the user's application, or on external boxes acting as routers or bridges.
dummynet runs within your operating system (FreeBSD, OSX, Linux, Windows) and works by intercepting selected traffic on its way through the network stack, as in the figure above, and passing packets to objects called pipes which implement a set of queues, a scheduler, and a link, all with configurable features (bandwidth, delay, loss rate, queue size, scheduling policy...).
Traffic selection is done using the ipfw firewall, which is the main user interface for dummynet. ipfw lets you select precisely the traffic and direction you want to work on, making configuration and use incredibly simple. You can create multiple pipes, send traffic to different pipes, even build cascades of pipes.]]></description>

    <dc:creator>mlednor</dc:creator><description><![CDATA[This tutorial will show you how to identify drivers causing high Deferred Procedure Call (DPC) latencies. Spikes of high DPC latency can cause a computer to slow to a crawl for a few seconds before speeding up again in super-speed to catch up, then repeating a number of seconds later. During the few seconds of slowness (high latency spike), you may notice jerky and erratic mouse movement, poor quality, stuttering, audio, and pausing and skipping in real time video playback. If these symptoms sound familiar, read on. 

The technique outlined below will work on Windows 7 and Windows 8. It will not work on Windows XP, but an alternative for Step II has been briefly outlined at the bottom of this tutorial for Windows Vista.

In addition, this technique is fairly technically advanced. Although it should be perfectly possible for anyone to complete provided you follow carefully the instructions given, if you require further clarification of any particular steps, or run into any sort of difficulties, please do not hesitate to ask us for help.]]></description>

    <dc:creator>mlednor</dc:creator><description><![CDATA[The depth and spread of tools and features in Adobe Photoshop CS6 and Photoshop CS6 Extended software make the two editions applicable to a variety of work environments and suitable for a wide range of tasks by image-makers of all skill levels, from enthusiasts to professionals. In some environments, Photoshop is employed in a dedicated, standalone fashion, while in others, it is a pivotal part of a larger suite of programs. Making sure that your computer meets the minimum system requirements is an essential first step in ensuring that all features function correctly. Optimizing your Photoshop CS6 setup to suit your work environment and the tasks you regularly perform is the next step. All users will benefit from such optimization, but those who work with video, 3D content, or other large files—or those who process multiple files at once—will see the greatest performance gains. This paper provides guidance on best practices to optimize Photoshop CS6 performance with a combination of careful hardware selection and informed program setup.

What type of Photoshop user are you?
Determining how you typically use Photoshop will help you make more informed decisions about the best ways to optimize your setup. For instance, the photographer who regularly processes high-resolution images will greatly benefit from increasing the amount of system RAM available to Photoshop, whereas the designer who works with 3D models will obtain far better performance by installing a faster video card containing more video RAM. So, itemize the tasks that you regularly perform in Photoshop and then use the recommended setup details contained in this paper as the basis for optimizing your system.

Essential hardware
Computers are built with a variety of components. Each performs a different function, and together they affect the overall performance of Photoshop.]]></description>

    <title>High-Performance WordPress with W3 Total Cache and Nginx | Eli Van Zoeren</title>
    <dc:date>2011-09-20T17:35:16+00:00</dc:date>
    <link>http://elivz.com/blog/single/wordpress_with_w3tc_on_nginx/</link>
    <dc:creator>mlednor</dc:creator><description><![CDATA[I recently set up a new server to host website for my clients. I took the opportunity to re-think how I have been serving sites and optimize the whole software stack for better performance. Rather than the usual LAMP (Linux/Apache/MySQL/PHP) stack, I decided to go with LEMP, switching Apache out for Nginx. Although most common PHP applications recommend Apache, they will actually run faster on Nginx. Usually all you just need to do is translate the .htaccess file rules into Nginx’s configuration file.

My first order of business once the new server was set up was to get WordPress running and to optimize its performance. The first few sites that would be going on the new hardware were using WordPress so although I will be going through a similar process for Expression Engine soon, WordPress was my test-case.

I always run the W3 Total Cache plugin with my WordPress installations. By storing copies of each rendered page to disk (as well as many other optimizations), W3TC dramatically decreases the load on the server under heavy traffic. This is particularly the case with the Nginx configuration I am about to show you, which lets most requests be handled by Nginx alone. Nginx was designed first and foremost as a reverse proxy, so it serves static files almost instantly and with minimal processor or memory usage. There are a number of sample configurations around the web for running WordPress with W3TC on Nginx, but none of them quite did it for me. For one thing, they all rely heavily on if statements, which are evil. So here is my take on it….

Through physical file realloction e4rat eliminates both seek times and rotational delays. This leads to a high disk transfer rate.
Placing files on disk in a sequentially ordered way allows to efficiently read-ahead files in parallel to the program startup. The combination of sequentially reading and a high cache hit rate may reduce the boot time by a factor of three, as the example below shows.

e4rat is based on the online defragmentation ioctl EXT4_IOC_MOVE_EXT from the Ext4 filesystem, which was introduced in Linux Kernel 2.6.31. Other filesystem types and/or earlier versions of extended filesystems are not supported.
