Further to , Reinhard Müller (reinhard) passed on some further info about performance issues in appserver and in gnue in general - over the weekend I was having a talk with another developer that was fighting performance issues in python, and this developer had the very same problem that garbage collection is *the* performance killer in python and close to impossible to optimize as it runs just at random times and it can't be easily found out which function causes which garbage. Derek Neighbours (derek) pointed to a good article on this subject that gave examples on how to avoid object churning. However, he noted that when we chose python the primary reason was - python values productivity over performance :) - is gnue to a point where it needs to consider optimization?. Jason Cater (jcater) did not think so - I think the question just came up in the context of some tests someone was doing with a new comm backend.
