Optimization
[edit]Swiftweasel is optimized using the following methods:
P.G.O.
[edit]As of the 3.0.3 release, Swiftweasel has shifted its primary optimization from processor specific to profile-guided optimization (PGO).[1] It is a two step building process. The application is compiled one time and then run to produce a profile. The profile is then used to guide a second compilation of the application. Some of the older optimizations are still used, but there are now only Intel and AMD versions of each build. It is released compiled in a tar.gz package. There are also separate installers for Ubuntu and Arch linux available through their communities.
Binary code optimization
[edit]- Swiftweasel is compiled with options that optimize for speed rather than binary size.
- Binaries incorporate additional instruction sets:[5]
- Optimization specific to the build microprocessor architecture.[5]
- Compiled with newer versions of GCC (Firefox 2.0 uses 3.3.2, Swiftweasel 2.0 uses 4.0.3, and Swiftweasel 3.0.3 uses 4.2.3).[5]
Increased Security
- Better protection from Buffer overflow attacks[6] (Swiftweasel 2.0 uses -D_FORTIFY_SOURCE=2; Firefox 2.0 uses gcc 3.x, which does not support this).[5]
Simplify
- IPv6 DNS lookups are disabled, preventing slowdowns;[5]
- HTTP pipelining is enabled by default.[5] Note that Fasterfox provides a GUI to adjust these settings.
- For full details, users can download source packages with all changes listed.
Installed extensions
[edit]Swiftweasel has several extensions installed by default.[7]
- XForms
- AdBlock Plus
- User Agent Switcher[8]
- Quick Locale Switcher[9]
Swiftweasel-specific changes
[edit]Changes made to Swiftweasel include:
- The default icon set has been replaced with the Kempelton[10] icon set.
- Swiftweasel uses its own settings directory. The settings, including bookmarks, history, and extensions are imported from Mozilla Firefox the first time Swiftweasel runs.
- Plugins stored in /lib/mozilla/plugins and /lib/Firefox/plugins are detected and used by Swiftweasel.
