Something faster than MS Access 2007, Fast Portable Database Recommendations?

Question

I'm using MS Access 2007 for insert and read data in my application but it's really slow.

I've got a long running application and if I run it from the memory it takes about 5 minutes, with MS Access 2007 it takes about 13 minutes!

I'm looking for a faster yet portable database option, I'm using .NET . I'm not looking for advanced relational database stuff, as soon as it works like a decent database, it's enough for me.

EDIT :

I'm mostly doing concurrent inserts from multiple threads.

RESULTS

I've tried SQL Server Compact Edition 3.5 SP1 and it's almost same with running from memory so %400 times faster than access + instead of a 72MB of dependency I've got 1.5MB dependency which is great.

P.S. Database is normalised, clean, compacted and I'm using stored_procedures and native client. So I've tried so many things to make it faster already.
