QAT Performance Issue

Hi Everyone,

       I have a performance issue about QAT.

       I run the test app in \openssl-async\apps\speed and record the result as below table.

As you see, the performance of QAT is poor.  Can someone please give me some advice?

Here is my test cmd:

QAT :                                 ./apps/openssl speed -engine qat -evp aes-128-cbc -elapsed

SW(disable a AES-NI) :     OPENSSL_ia32cap="~0x200000200000000" ./apps/openssl speed -evp aes-128-cbc -elapsed

SW-Using AES-NI:            ./apps/openssl speed -evp aes-128-cbc -elapsed

HW Spec:

Platform :    Rangeley

CPU       :    Intel(R) Atom(TM) CPU  C2758  @ 2.40GHz
