This is fine. We will run some query examples based on Xmark. We will compare the results of several queries with eXist. It will be similar to here (unfortunately smaller scale): http://monetdb.cwi.nl/XQuery/Benchmark/XMark/
To get new insights, it would be nice if you could include some other DBs as well, but the given time restrictions won't probably allow to do more.
I am thinking to run it on three different sizes of Xmark generated database: 1.1MB, 11MB, 110MB. Any hints/suggestions/requests here? Note that both systems are running on client/server mode.
You could think about including at least 1GB instances (as a side note, we'd created XMark instances up to 55GB).
Looking forward to the results, Christian
