Displaying Roadmap takes over 17 seconds for a medium size Project with Redmine 1.2.1
with advanced roadmap version 0.5.1 it takes over 17 seconds for displaying the roadmap
for a medium sized project (4 Versions, about 100 issues) .
I guess this is not the usual waiting time for it so it may be a bug.
Also the pie chart is not displayed at all. It might have something to do with that.
