--- Comment #2 from Uli Schlachter <psychon at znc.in> ---
And valgrind --tool=callgrind says that 65% of CPU time is spent inside
gnm_style_borders_row_draw() (unrelated code?) which itself spends most of its
cpu time in cairo_stroke(). So the high cpu usage seems to come from some
unrelated code which just happens to be executed more often due to the "ant
lines".
I don't see why this would be a cairo problem. Could you provide more
information, perhaps some self-contained C code that shows cairo being slow?
