I've tried using it in the past and although I could get it compiled  
and running, it seemed to be unstable and failed to work correctly in  
certain situations -- it was a long time ago, don't ask for details.

However, because of that first bad experience and the fact that I  
haven't heard of any development on the php module, I gave up using it  
and I'm using system() calls to run rrdtool from a php script.

Does anyone know, if there's any _considerable_ performance  
degradation by using system() calls instead of having internal calls  
directly to the rrdtool functions?
