NHibernate Performance Testing

Here are results from performance tests run on SQLite and MySQL database.

Local machine is Windows Vista 64 bit with Quad Core processor with 4G memory. MySQL has factory settings.

Remote mysql database machine is Ubuntu Linux virtual machine with one virtual processor and 2G memory. MySQL has factory settings.

Local machine ping is 10 ms to the remote machine.

Performance test is execute with NAnt and .NET-framework 2.0.

Results with Empty Tables
