The last days I was trying to install and run the xhprof. I finally made it and I think that it brings up very interesting information. I also installed graphviz and I can generate nice graphs, but I would like to find a documentation explaining what the colors in the graphs mean? What does exactly mean each column of the profiler report and how is it calculated.
I was trying to find something the whole day, but unfortunately the only information that I found were usage documentation.
Does any of you have such documentation or know a link? This link seems to be broken...
