> It's probably outside the scope of this ticket, but the ''really''
useful thing would be if `%prun ...` in the notebook would return an
interactive browser for the `Stat` object that is returned by
`cProfile().runctx(...)`. While a basic printout of profiling data gives
some indication, one usually needs to dig around a little in the data to
find what the real bottleneck is (see where most calls come from, switch
between cumulative and proper time, etc.)
+1/2 since being able to read/interpret the raw data is a good skill to
have IMO. However a graphical (or at least a tree structure) of the data
is also very useful.

interested in interface programming. I bet there are good profiler
browsers around to get inspiration from.
+1 here. I feel like we need a wiki page to keep a list of "good student
projects"...
> A tool I haven't used yet but looks like a decent effort is
[https://pypi.python.org/pypi/RunSnakeRun runsnakerun]. Duplicating that
effort for the sage notebook might not seem like such a smart idea.
Perhaps we can make the tool more easily accessible from sage? Given that
it uses wxPython that might not be so very easily done ... I ended up
installing it using OS tools, meaning that I ''have'' to write the profile
data to a file and analyse it separately.
I've seen runsnakerun used in a few places (although I haven't used it
myself), and instead of duplicating it in the notebook, perhaps we could
link it into sage (notebook) as some type of package? Actually...perhaps
what we should do is have a variable/function which calls your favorite
profiler on the executed command(s), something like:
{{{
%profile
2 + 2
}}}
