Question

I test the speed of RSA-2048 and ECDSA-256 of mbedtls(2.6.1) and openssl(1.1.0f), at raspberrypi with arm7.
Here is the result (sign/verify in ops/s) :

         ras2048  ecdsa256
mbedtls  21/823    150/47
openssl  36/1363  1437/718

where mbedtls is much slower than openssl both.
I test this on x86_64 and get similar result, but I do not have the result by now.

I build mbedtls with the default config.h.
Is the result right?

With another issue I posted, I want to ask that, have you benchmarked mbedtls and compared with openssl? Do you care about the performance of mbedtls?

Thanks,
Wu

Hi @WuBingzheng Thank you for raising this!
As I answered in the other issue, we will investigate this.
