    QAT Performance Issue

    SamChang Community Member

      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
