I've now implemented it (took me two days of debugging %-( ), but the problem is still there:
Reading the list takes forever, but display is now ok.

I integrated some simple profiling code, and the results are the following:

92 objects
Time to read object from database: 0.4-0.8 sec (= 1.25-2.5 obj per sec)
Time for further processing: 0.05 sec
Total time: 77 sec

Which is rather slow for a 300MHz G3. A regular database would get about 1000 entries per sec, not 2...
