If you need performance, take a look at the z3c.indexer package which offers a much faster indexing concept. I implemented this package because my app coudn't handle the implicit default indexing handling. The README.txt explains what is different and how to use it. It defently needs some work to implement a z3c.indexer based indexing concept but if you do it right, it can handle a lot more indexing tasks then the generic zope or zc.catalog concept. Here are some performance data: z3c.indexer indexer based indexing time: 2.47 s zope.catalog catalog based indexing time: 14.41 s btw, You can run the performance test by yourself located in the z3c.indexer package.
