XFT: Works but slow

As seen from the version info below, I compiled the CVS HEAD XEmacs with newgc and xft few days ago. I am mostly surprised how well it has worked. It hasn't been crashing constantly. I use XEmacs to read my mail and some newsgroups with nntp with Gnus and I have done it for a long time from work by running XEmacs remotely from my home computer over X protocol. Now --with-xft it is almost unusable slow when used that way. The repaints take seconds and can be seen quite well. ,---- | uname -a: Linux iny.iki.fi 2.6.14-1.1656_FC4smp #1 SMP Thu Jan 5 22:24:06 EST 2006 i686 i686 i386 GNU/Linux | | ./configure '--prefix=/opt/xemacs' '--enable-mule' '--enable-widgets=athena' '--enable-dialogs=athena' '--with-socks' '--without-canna' '--without-wnn' '--enable-newgc' '--with-xft=emacs, menubars, tabs, gauges' | | | XEmacs 21.5-b24 "dandelion" (+CVS-20060123) configured for `i686-pc-linux'. | | Compilation Environment and Installation Defaults: | Source code location: /home/biny/packages/repositories/xemacs | Installation prefix: /opt/xemacs | Operating system description file: `s/linux.h' | Machine description file: `m/intel386.h' | Compiler version: gcc (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8) | - GCC specs file: specs. | - Compiler command: gcc -Wall -Wno-switch -Wundef -Wsign-compare -Wno-char-subscripts -Wpacked -Wunused-parameter -g | libc version: glibc-2.3.5-10.3 | Relocating allocator for buffers: no | GNU version of malloc: yes | - Using Doug Lea's new malloc from the GNU C Library. | | Window System: | Compiling in support for the X window system: | - X Windows headers location: /usr/X11R6/include | - X Windows libraries location: /usr/X11R6/lib | - Handling WM_COMMAND properly. | - Compiling in support for Xft antialiased fonts (EXPERIMENTAL). | Compiling in support for the Athena widget set: | - Athena headers location: X11/Xaw | - Athena library to link: Xaw | Using Lucid menubars. | - Using Xft to render antialiased fonts in menubars. | WARNING: This feature will be replaced with a face. | Using Lucid scrollbars. | Using Athena dialog boxes. | Using Athena native widgets. | - Using Xft to render antialiased fonts in tab controls. | WARNING: This feature will be replaced with a face. | - Using Xft to render antialiased fonts in progress bars. | WARNING: This feature will be replaced with a face. | WARNING: This feature not yet implemented; setting ignored. | | TTY: | Compiling in support for ncurses. | Compiling in support for GPM (General Purpose Mouse). | | Images: | Compiling in support for GIF images (builtin). | Compiling in support for XPM images. | Compiling in support for PNG images. | Compiling in support for JPEG images. | Compiling in support for TIFF images. | Compiling in support for X-Face message headers. | | Sound: | Compiling in support for sound (native). | | Databases: | Compiling in support for Berkeley database. | Compiling in support for LDAP. | Compiling in support for PostgreSQL. | - Using PostgreSQL header file: libpq-fe.h | - Using PostgreSQL V7 bindings. | | Internationalization: | Compiling in support for Mule (multi-lingual Emacs). | Compiling in support for XIM (X11R5+ I18N input method). | - Using raw Xlib to provide XIM support. | | Mail: | Compiling in support for "file" mail spool file locking method. | | Other Features: | Inhibiting IPv6 canonicalization at startup. | Compiling in support for SOCKS. | Compiling in support for dynamic shared object modules. | Using the new GC algorithms. | WARNING: --------------------------------------------------------- | WARNING: The new algorithms are experimental.
