The re-compiled Firefox is much faster.

The re-compiled Firefox is much faster-the Linux Release Technology-Debian information. The following is a detailed description. Since I upgraded Debian from lenny to sid, the speed of my IceWeasel (Firefox) has become incredibly slow, especially when using Google Reader and Gmail. Today finally unbearable, to the http://releases.mozilla.org/pub/mozilla.org/ to download the Firefox 3 Beta 3 source code compilation. The attempt to use ICC as a compiler always reports a strange compilation error about dynamic_cast somewhere. Give up and switch to GCC. (I used apt-build in combination with ICC to successfully compile iceweasel, but a segment error occurred during the runtime. Why can't I pass it now ?) After compilation, Firefox is much smoother (this time is definitely not a psychological effect ...), I don't know whether this is due to recompilation or Firefox 3's improvement.

Compilation options:
$ Export CC = 'gcc-march = prescott-msse3-fomit-frame-pointer'
$ Export CXX = 'G ++-march = prescott-msse3-fomit-frame-pointer '(both gcc and g ++ are 4.2.3)
$ .. /Mozilla/configure -- enable-application = browser -- disable-nls -- disable-updater -- disable-crashreporter -- disable-mathml -- enable-official-branding -- with-system-jpeg -- -system-zlib -- with-system-nspr -- with-system-nss
$ Make-j2
$ Su
# Make install

-- With-system-png cannot be used. The system libpng does not support APNG (Animated PNG); -- with-system-cairo also fails, and the libcairo version of the system itself is not enough ......
