QAT + OPENSSL 1.1.1q performance

I have been trying to reproduce the numbers published by intel on my setup.
[https://01.org/sites/default/files/downloads/intelr-quickassist-technology/337003-001-intelquickassisttechnologyandopenssl-110.pdf ](url)
In the above document Table 2. Performance of RSA 2K with OpenSSL speed it is mentioned that sign/s is around 100k and verify/s is around 200k. The numbers I get for verify/s are similar but for sign/s I get around 27k and for ecdsap256 both sign/s and verify/s are lower than what is mentioned in the document.
here's a document in which I have mentioned the steps I followed and the results.I have also added the software runs for both the cases. I am using c62x chipset with Quickassist.

Need help to figure out why the performance is low.
