WordPress Benchmark: 3.0 vs 3.1 vs 3.2 vs 3.3

WordPress now has 4 versions in 3.x line. With slow adoption rate for previous two major versions, despite great 3.2 release, question is will the new WordPress 3.3 manage to persuade users to upgrade? This benchmark will try to give, at least, partial answer to that.

On of the things I want to do with backups is to add encryption of files inside the archive, mainly database and some of source files at least. But, web servers and PHP is not really well suited to handle any type of encryption due to complexity and limited resources for such operations.
WordPress Benchmark: 3.0 vs 3.1 vs 3.2

With release of new WordPress 3.2, it’s very interesting to see benchmarked performance of last 3 major versions, and how far the new WordPress has come. This is first benchmark post with the results of the performance of the WordPress administration side. Second one coming in the next couple of days.
Custom posts filtering with taxonomy terms
Only when you get to work on a really huge WordPress website with hundred thousands of posts, post tags and other elements, you will realize that many operations you think as common are going to get very, very slow even on very powerful servers. What to do than?









WordPress Benchmark: 3.0 vs 2.9.2, Part 3
Third benchmark is used to measure the performance on the actual website or blog side visible to all visitors. Since WP 3.0 has a new theme, test was expanded here to include both Kubrick and Twenty Ten themes under WP 3.0, and only Kubrick under WP 2.9.2.
