-Hi,
-
-Last month, Xan xtraced[1] cairo text drawing (using xlib), and noticed
-that cairo creates (and afterward destroys) a 1x1 pixmap (a cairo
-surface) every time it draws some text. Xft doesn't do this.
-
-Carl and Behdad suggested ways to, like Xft, cache surfaces so as not to
-have to recreate them all the time.
-
-As suggested by Carl in the same thread, I first investigated
-per-pattern caching of acquired surfaces. This didn't work as patterns
-mostly get copied before their surfaces are requested. 
-
-Attached patch adds a simple 16-entry static cache to
-_cairo_pattern_acquire_surface_for_solid(). It still needs work, however
-this already yields a speedup[2] of 12% when drawing text using GTK+
-2.10, exceeding the performance of GTK+ 2.6. Yay!
-
-Comments appreciated,
-
-Jorn
