SQL Server CE 4.0 performance comparison

SQL Server CE 4 (SQL Server Compact Edition 4.0) is not news already (If it is, you could read this article)

But it is very interesting to see SQL Server CE 4 performance comparison to other databases.

Especially with:

• SQLite
• SQL Server (1)
• SQL Server Express *
• maybe Firebird

(1) for applications where functionality is comparable.

Unfortunately there are not so much links about the subject that google provides right now. Actually I was unable to find any (for proper SQL CE version).

If one could find or share such information lets collect it here for future humanity.
