Swiftweasel was a
Optimization
Swiftweasel is optimized using the following methods:
P.G.O.
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
- Swiftweasel is compiled with options that optimize for speed rather than binary size.
- instruction sets:[5]
- Optimization specific to the build microprocessor architecture.[5]
- Intel 32bit: Pentium 4 (Prescott), Pentium 4, Pentium M, Pentium III, Pentium II;
- Nocona;
- K6-2, Athlon;
- Athlon64, Opteron.
- 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
- DNS lookups are disabled, preventing slowdowns;[5]
- GUIto adjust these settings.
- For full details, users can download source packages with all changes listed.

Swiftweasel-specific changes
