[Discuss] images of comparison of system calls; impressive

I wouldn't read too much into that article. They claim the calls are
syscalls yet you can't even read the image to figure out if they are are
actually system calls and not just call graph.

Also they are comparing 2 different web servers who have radically
different architectures. For instance many heavy duty apache modules
will be dynamically loaded. Did they extract all the calls from that?
Also they aren't clear about what the links are and which direction they
go. Notice how it seems hard to find the root of the graph or where it
starts.

The whole article is misleading and not very verifiable.
