Caching Tutorial for Web Authors and Webmasters

, 1 comment
A Web cache sits between one or more Web servers (also known as origin servers) and a client or many clients, and watches requests come by, saving copies of the responses — like HTML pages, images and files (collectively known as representations) — for itself. Then, if there is another request for the same URL, it can use the response that it has, instead of asking the origin server for it again.
How To Optimize Your Site With HTTP Caching | BetterExplained

Caching is a great example of the ubiquitous time-space tradeoff in programming. You can save time by using space to store results.
In the case of websites, the browser can save a copy of images, stylesheets, javascript or the entire page. The next time the user needs that resource (such as a script or logo that appears on every page), the browser doesn’t have to download it again. Fewer downloads means a faster, happier site.

Tools for Performance Tuning and Optimization | 2bits.com, Inc. - Drupal Development, Customization and Consulting

When tuning a site's performance, a system administrator needs certain tools to measure and monitor how the site is doing under increasing load, as well as identify where bottlenecks may be.

Apache prefork, StartServers, MaxSpareServers and MinSpareServers
In the most common case, you will be using Apache in the prefork mode, meaning one process per connection, with a pool of processes pre-forked to standby for connections. The number of spare processes is defined by the values MaxSpareServers, MinSpareServers, while the number to start is defined by StartServers.

Power PostgreSQL - PerfList
by ogrisel
(via)
This is a set of rules of thumb for setting up your PostgreSQL 8.0 server. A lot of the below is based on anecdotal evidence or practical scaling tests; there's a lot about database performance that we, and OSDL, are still working out. However, this should get you started. All information below is useful as of January 12, 2005 and will likely be updated later. Discussions of settings below supercede the recommendations I've made on General Bits.

Surviving 100,000 instant Visitors on a Budget
by holyver

Last Sunday I casually wrote a post about the most common pitfalls in photography. I had written the post a long time ago, but I never put it on this site.
The story ended up on the front page of Digg, stayed there for nearly 12 hours and was picked up by a bunch of secondary sources, resulting in 100,000 Visitors within a day (most of them within the first 12 hours). Trying to keep my server up and alive, I learned a lot about what it takes to keep the server alive, hence I decided to slide a non photography related post in, hopefully giving everyone who finds themselves in a similar situation some points to consider.
