The new gnome-screensaver in 2.14 is unbelievably slow. On my 1GHz system it takes over 20 seconds to bring up the password window. I can't imagine what it is doing all of this time. The screen un-blanks and the cursor appears almost instantly, but it just sits there at that point. On my 2GHz system, it 'only' takes about 6 seconds and my Athlon-64x2 4400+ even takes about 4 seconds.

Anyone have any idea what is going on? Waiting 22 seconds is simply painful! I have same problem, It incredible slow when there is some other activity (buildworld in background for example). Looks like it requires too much pages to show input window, and all theses pages thrown out while other activity and then loaded too slow. I have idea why it happens, looks like gnome-screensaver execs /usr/X11R6/libexec/gnome-screensaver-dialog on activation event And binary starts to map whole big set of libraries: % ldd /usr/X11R6/libexec/gnome-screensaver-dialog /usr/X11R6/libexec/gnome-screensaver-dialog: libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x28095000) libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x2809d000) libXss.so.1 => /usr/X11R6/lib/libXss.so.1 (0x280b3000) libXxf86vm.so.1 => /usr/X11R6/lib/libXxf86vm.so.1 (0x280b6000) libXxf86misc.so.1 => /usr/X11R6/lib/libXxf86misc.so.1 (0x280bb000) libgtk-x11-2.0.so.0 => /usr/X11R6/lib/libgtk-x11-2.0.so.0 (0x280be000) libgdk-x11-2.0.so.0 => /usr/X11R6/lib/libgdk-x11-2.0.so.0 (0x28369000) libXrandr.so.2 => /usr/X11R6/lib/libXrandr.so.2 (0x283e2000) libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x283e6000) libXinerama.so.1 => /usr/X11R6/lib/libXinerama.so.1 (0x283ee000) libatk-1.0.so.0 => /usr/local/lib/libatk-1.0.so.0 (0x283f1000) libgdkpixbuf-2.0.so.0 => /usr/X11R6/lib/libgdkpixbuf-2.0.so.0 (0x28409000) libpangocairo-1.0.so.0 => /usr/X11R6/lib/libpangocairo-1.0.so.0 (0x2841d000) libXcursor.so.1 => /usr/X11R6/lib/libXcursor.so.1 (0x28425000) libXfixes.so.3 => /usr/X11R6/lib/libXfixes.so.3 (0x2842e000) libcairo.so.2 => /usr/local/lib/libcairo.so.2 (0x28433000) libpng.so.5 => /usr/local/lib/libpng.so.5 (0x2847b000) libpangoft2-1.0.so.0 => /usr/X11R6/lib/libpangoft2-1.0.so.0 (0x2849e000) libfontconfig.so.1 => /usr/X11R6/lib/libfontconfig.so.1 (0x284c3000) libexpat.so.6 => /usr/local/lib/libexpat.so.6 (0x284ef000) libfreetype.so.9 => /usr/local/lib/libfreetype.so.9 (0x2850d000) libpango-1.0.so.0 => /usr/X11R6/lib/libpango-1.0.so.0 (0x28572000) libXrender.so.1 => /usr/X11R6/lib/libXrender.so.1 (0x285a9000) libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x285b1000) libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x28672000) libgnomevfs-2.so.0 => /usr/X11R6/lib/libgnomevfs-2.so.0 (0x2867f000) libxml2.so.5 => /usr/local/lib/libxml2.so.5 (0x286d9000) libz.so.3 => /lib/libz.so.3 (0x287e1000) libssl.so.4 => /usr/local/lib/libssl.so.4 (0x287f2000) libcrypto.so.4 => /usr/local/lib/libcrypto.so.4 (0x2882a000) libavahi-glib.so.1 => /usr/local/lib/libavahi-glib.so.1 (0x2893c000) libavahi-client.so.3 => /usr/local/lib/libavahi-client.so.3 (0x2893f000) libdbus-1.so.2 => /usr/local/lib/libdbus-1.so.2 (0x2894d000) libavahi-common.so.3 => /usr/local/lib/libavahi-common.so.3 (0x2897e000) libutil.so.5 => /lib/libutil.so.5 (0x28988000) libbonobo-2.so.0 => /usr/local/lib/libbonobo-2.so.0 (0x28994000) libgconf-2.so.4 => /usr/X11R6/lib/libgconf-2.so.4 (0x289e4000) libbonobo-activation.so.4 => /usr/local/lib/libbonobo-activation.so.4 (0x28a12000) libORBitCosNaming-2.so.0 => /usr/local/lib/libORBitCosNaming-2.so.0 (0x28a25000) libORBit-2.so.0 => /usr/local/lib/libORBit-2.so.0 (0x28a29000) libpopt.so.0 => /usr/local/lib/libpopt.so.0 (0x28a7f000) libgobject-2.0.so.0 => /usr/local/lib/libgobject-2.0.so.0 (0x28a86000) libm.so.4 => /lib/libm.so.4 (0x28abb000) libgmodule-2.0.so.0 => /usr/local/lib/libgmodule-2.0.so.0 (0x28ad0000) libgthread-2.0.so.0 => /usr/local/lib/libgthread-2.0.so.0 (0x28ad3000) libglib-2.0.so.0 => /usr/local/lib/libglib-2.0.so.0 (0x28ad7000) libintl.so.6 => /usr/local/lib/libintl.so.6 (0x28b56000) libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x28b5f000) libcrypt.so.3 => /lib/libcrypt.so.3 (0x28c4c000) libpthread.so.2 => /lib/libpthread.so.2 (0x28c64000) libc.so.6 => /lib/libc.so.6 (0x28c89000) % Very probably, that part of them already thrown out from memory, and should be reread from disk.

Thanks for the explanation. This kind of thing will not be unique to FreeBSD. I recommend you open a bug in GNOME Bugzilla if one does not already exist.
