Here we go… ruby-prof said wxRuby was spending a lot of time initializing memory device contexts (canvases to draw on)…
%self total self wait child calls name
45.42 5.63 5.63 0.00 0.00 120 Kernel#sleep
8.85 2.05 1.10 0.00 0.95 28440 WxRubyStyleAccessors#method_missing

4.42 5.14 0.55 0.00 4.59 9520 Wxruby2::Bitmap#draw
That would be because I was doing so before each line I drew.
def draw_line(options = {})
buffer.draw do |surface|
surface.pen = Wx::Pen.new(
...
end
end
So as a quick fix, I’m queueing my shapes and drawing everything at once. This brought me about in line with Ruby-Gnome2, speed-wise:
def draw_line(options = {})
@line_queue << options
end
def render_lines
buffer.draw do |surface|
while options = @line_queue.shift do
surface.pen = Wx::Pen.new(
...
end
end
end

Though I made a pretty big memory structure to do it. I’ll have to slim that down at some point.
Now it says it’s spending a lot of time initializing colors (Colours?) and pens. Will I have to cache those? Hope not.
