Hmmmm, can you show an example for which it is much slower?

It should not be slower at all. See e.g. this thread:
http://lists.gnu.org/archive/html/igraph-help/2009-06/msg00091.html

I would definitely go with the R or Python version, the one that you
are more familiar with. R and Python are _much_ more productive than
programming in C. Only use C if you really need to.
