Swiftfox

The Swiftfox build is optimized using the following methods: Binary code optimization • Compiled with the highest level of compiler optimization, rather than optimization for binary size. • Swiftfox is compiled -O3, (the highest level) • The resulting Swiftfox binary is larger than Firefox. (-O3 is not necessarily faster than -O2, or -Os. -O3 introduces two more options on top of -O2: -finline-functions and -frename-registers. The latter is good for CPUs with many registers but may actually be slower on other CPUs.) • Firefox is compiled -Os. • Intel and AMD: MMX, SSE, SSE2, (not generally SSE3). • AMD only: 3DNow! • Optimization specific to the build microprocessor architecture. (Swiftfox 2.0 uses -D_FORTIFY_SOURCE=2; Firefox 2.0 uses gcc 3.x, which does not support this). provided by Pango. This simplification reduces the binary size, and reduces rendering. Changed default preference values • IPv6 DNS lookups are disabled. preventing slowdowns experienced • HTTP pipelining is enabled by default. Fasterfox provides a GUI to adjust these settings. • For full details, see . == Swiftfox speed ==

No definitive benchmarking has been reported, but a quicker startup time and a 1.7% webpage rendering speedup has been reported on version 1.5.0.6. There are no benchmarks for the different processors builds. == Additional options ==

Swiftfox is bundled with the following freely available Firefox plugins and extensions: • XForms extension is installed and enabled • libunixprintplugin.so plugin is installed == License ==

The same as Firefox, the Swiftfox source code is open-source, with the source code under MPL 1.1 except for parts relating to branding. which does not allow redistribution. According to the author, this is to prevent the possibility of any confusion with tainted versions (see the Firefox branding argument Mozilla Firefox#Trademark and logo). The name Swiftfox is trademarked by Jason Halme, and accordingly cannot be used on other third party Firefox builds without his permission. Debian Swiftfox binaries are available as Debian packages from official site. The proprietary binary license prevents Debian and other Linux distributions from having Swiftfox available as part of a distribution, so to redistribute Swiftfox one would have to change the name and icons. == See also ==
