I happen to like www.markfiore.com (a Flash-heavy opinion site), but it has annoyed me for some time that his movies appear to play rather slowly. It turns out that, if I download the movie using wget and then play it through gflashplayer, it plays faster, to the extent that the snippet ends before the music runs out. Games from www.miniclip.com also tend to run slowly on my system. It's not a CPU problem since I also have the System Monitor applet, and it's showing very little if any CPU usage while it's playing the movie. Reproducible: Always Steps to Reproduce: 1. emerge mozilla and netscape-flash 2. bring up a website with Flash 3. download the same movie using wget (or equivalent) and play it in gflashplayer Actual Results: The mozilla variant runs more slowly. Expected Results: Mozilla and gflashplayer should play the movie back at the same speed, or at least close enough. $ emerge info Portage 2.0.50-r8 (default-x86-1.4, gcc-3.3.3, glibc-2.3.3.20040420-r0, 2.4.26-gentoo-r3) ================================================================= System uname: 2.4.26-gentoo-r3 i686 AMD Athlon(TM) XP 1600+ Gentoo Base System version 1.4.16 distcc 2.13 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled] Autoconf: sys-devel/autoconf-2.59-r3 Automake: sys-devel/automake-1.8.3 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O2 -mcpu=athlon-xp -march=i686 -pipe" CHOST="i686-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.2/share/config /usr/kde/3/share/config /usr/lib/mozilla/defaults/pref /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/lib/jboss /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -mcpu=athlon-xp -march=i686 -pipe" DISTDIR="/data/distfiles" FEATURES="autoaddcvs buildpkg ccache distcc sandbox" GENTOO_MIRRORS="http://gentoo.oregonstate.edu http://distro.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j3" PKGDIR="/usr/portage_packages.aurigae" PORTAGE_TMPDIR="/data/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="3dnow X aalib acpi acpi4linux alsa apm arts avi berkdb cdr crypt cups encode esd foomaticdb gdbm ggi gif gnome gnomedb gpm gtk gtk2 guile imlib ipv6 java jpeg kde libg++ libwww mad mikmod mmx motif mozilla mpeg nas ncurses nls oggvorbis opengl oss pam pdflib perl png postgres ppds python qt quicktime readline sdl slang spell ssl tcltk tcpd tetex truetype video_cards_fglrx video_cards_radeon x86 xml2 xmms xv zlib"

Stale bug, reopen if this still is an issue with up-to-date mozilla version.
