GtkPerf is an application designed to test GTK+ performance. The point is to create common testing platform to run predefined GTK+ widgets (opening comboboxes, toggling buttons, scrolling text etc.) and this way define the speed of device/platform.

Just found this and thought i had to share it:

Firefox insists on doing huge amounts of I/O when closing, as well as act slow when using the awesomebar, try the following (close down Firefox completely first):

for f in ~/.mozilla/firefox/*/*.sqlite; do sqlite3 $f ‘VACUUM;’; done

From Techthrob.com:

Preload is an "adaptive readahead daemon" that runs in the background of your system and observes what programs you use most often, caching them in order to speed up application load time. By using Preload, you can put unused RAM to good work, and improve the overall performance of your desktop system. Best of all, it's easy to install and use!

One of the first things I noticed after using Ubuntu for a while was how snappy the OS is, especially compared to Windows Vista (which in my experience can't even keep up with its predecessor XP). Then I poked around the Linux forums a little bit and found out that I could work even faster in Ubuntu by changing some default settings, and using a few of the OS's unique keyboard shortcuts.

I wrote about the performance of KDE 4 some time ago, and I'd like to revisit it. After a few threads about debug builds and release builds on kde-core-devel I figured I was wrong in my previous entry, KDE 4 couldn't easily be build without debugging symbols. So my build WAS a debug build. But now it's possible to have it clean and fast, and I did indeed see an increase in performance when trying it.

After some raving blogs about how memory-efficient and fast KDE 4 is, I decided to test something myself.

Early testing has shown that Ubuntu, when run as a virtual guest taking advantage of the new paravirt-ops paravirtualization interface, delivers as promised: it runs faster and more efficiently that it would as an unmodified guest. Ubuntu, a Linux distribution maintained by corporate sponsor Canonical Ltd., is the first commercially shipping operating system to support the paravirt_ops standard.

My Ubuntu Box was running slower than I thought I could tweak it, so what I did was look for some good patchsets and I seen some conflicting results with cfs and ck and decided to test a few benchmarks and the ck patchset is a little more responsive than cfs on my system.
