Philipp> Did anybody play with XML compressors for Zope or at least have Philipp> a hint how to do that? I use a slightly modified version of Fredrik Lundh's xmlrpclib.py module that will often use zlib compression to compress responses. Running over a wide area network such as the Internet I've seen speedups of as much as 5-to-1. Instructions and my current version of xmlrpclib.py are available from my Python Bits page: http://www.musi-cal.com/~skip/python/ I believe it is a drop-in replacement for Zope's version, though note that my code has other mods as well (in particular, it specifies the encoding as Latin-1 for all requests and responses). You should compare it with the versions distributed with Zope or by PythonWare to decide what changes you want to incorporate in your own system. -- Skip Montanaro (skip@mojam.com) http://www.mojam.com/ http://www.musi-cal.com/
