Hi,I have just started using openssl for my project. I'm building small server
application using intel QAT engine.1) I'm trying to find benchmark numbers for
pure hardware based comparison between with or without QAT engine. I mmap the
file which server will send (to eliminate disk performance). Any pointer where
to find would be appreciated.2) I'm also trying to check if there is hardware
based comparison between tcp vs tls. How much performance degradation I should
expect when I start using tls instead of tcp(given it is small embedded server
which is mmapping the file). I tried googling it and everywhere is mentions
that there is no to very little performance effect between TCP & TLS but that
is not what I see. I see performance degradation of magnitude of 10 times. I
use per core measurement. For single core if TCP performance is 50K CPS per
core and throughput is 10Gbps, when I modify it to use TLS 2048 RSA with AES
performance foes down to ~1Gbps and 300CPS for 128K file download. I'm using
home grown tcp stack and also bypassing linux kernel for networking.
Thanks,Amy
