| 649 The QCE engine does not appear to scale as well as the CPU to handle 650 multiple crypto requests. While the ipq40xx chips have 4-core CPUs, the 651 QCE handles only 2 requests in parallel. 652 653 Ipsec throughput seems to improve when disabling either family of 654 algorithms, sharing the load with the CPU.
