Oracle Database Express Edition (XE)

My buisness would like to use Oracle XE as a starter base installation for customers, so that they can easly upgrade to an full Oracle SE or EE later. However I fail to find benchmark tests (like tpc.org) which give an image of the performance of the Oracle XE and how it compares to other databases such as PostgreSQL or MySQL in the smaller application market segment that XE is targeting.

We have been running som tests in house, but the currently I must say they are not in the Oracle XE favour. This is disapointing, as we would want to avoid for our customers to start of with a DB other than Oracle, then do an transistion to Oracle SE or EE when the need is there.

We are working on tuning/optimizing the database to perform better. Nevertheless it would be really interesting to see some benchmarks / comparison of the performance between Oracle XE an other DBMS in this segment of the DB market. Beeing well aware that their is not necessarely one database that fits each application/segment best, such a test would be informative. And also great input for my company when choosing which DB to use. Does anyone have any experience on this subject any feedback is highly appreciated. If anyone is interested I would be glad to post details regarding our tesing in house.

Cheers
