Driver Comparison
The performance metrics in 230HTable 3 may help you determine which driver mode best suits
your application requirements. The measurements were taken using an Intel P4 2.8 GHz-
based PC with hyperthreading, 512 MB of memory, and Windows XP.
Although CPU performance and data transfer rates vary with PC configuration, relative
performance is roughly equivalent, independent of the PC.

CPU Usage < 1% < 15% 50%
With the hyper threading CPU used in these tests, the 50% CPU usage measured for the
Native Windows stack indicates that one complete processing thread was employed to
transfer the data. This leaves only one thread available for processing applications. By
contrast, with the DALSA NetLink Universal IP Filter Driver and the DALSA NetLink
High-Performance IP Device Driver, one complete thread and most of the second thread
are available for applications processing.
