If you experience packet drops in the Napatech host buffer and have already increased the buffer size to 1024 (see <Document 1934414.1> on more details), then this article can be used to optimize CPU usage in the system. This enhances the performance on the "rat" subsystem that reads data from the Napatech buffer, and if the data is read fast enough, then overflows/drops in the host buffer can be avoided.
