Re: [ZODB-Dev] anecdotal speed comparison with RelStorage

Well, the point was that RelStorage-to-Oracle was of similar speed to FileStorage-over-ZEO, meaning there are no performance reasons not to head for the former. Oracle win. ;) I've seen evidence that RelStorage on MySQL even has a chance of beating plain FileStorage in performance. Cool :-) I'd be really interested to try some tests with multiple ZEO clients attached to a FileStorage versus multiple RelStorage client attached to Oracle. I suspect Oracle would win ;-) I am certainly interested in hearing the results of that test. This might happen tomorrow, we'll see...

[ZODB-Dev] Problems installing ZODB under Windows
Hello, I have some troubles installing ZODB under Windows with Python 2.5.1. Benji York recommended to post here. The following it the problem: I downloaded the egg file for ZODB from http://pypi.python.org/packages/2.5/Z/ZODB3/ZODB3-3.8.0-py2.5-win32.egg#md5=2a7c8eb2ad6304a859ffdf5e2b9a075f and tried to install it with easy_install. It quits with the following message: Installed c:\python25\lib\site-packages\zodb3-3.8.0-py2.5-win32.egg Processing dependencies for ZODB3==3.8.0 Searching for zope.interface Reading http://pypi.python.org/simple/zope.interface/ Reading http://zope.org/Wikis/Interfaces/FrontPage Best match: zope.interface 3.4.1 Downloading http://pypi.python.org/packages/source/z/zope.interface/zope.interface-3.4.1.tar.gz#md5= b085f4a774adab688e037ad32fbbf08e Processing zope.interface-3.4.1.tar.gz Running zope.interface-3.4.1\setup.py -q bdist_egg --dist-dir c:\docume~1\holtza\locals~1\temp\easy_ install-9zm01c\zope.interface-3.4.1\egg-dist-tmp-8pfxjw error: Setup script exited with error: Python was built with Visual Studio 2003; extensions must be built with a compiler than can generate compatible binaries.

Can somebody please create an egg for zope.interfaces 3.4.1 and other dependencies of ZODB? Will I have the same problems if I install the complete zope framework? I don't want to install Visual Studio or any other C-compiler.
