Hi Team, I want to test openssl performance with and without using cryptodev driver.I tried 2 things but my both cases are fluctuating. *1. "Openssl speed test" with and without HW* When i am running openssl speed test using the below command, "openssl speed -evp aes-128-cbc" *I am getting outstanding improved performance difference in openssl while using with the cryptodev engine*.Below are the the numbers. Without Cryptodev =========== The 'numbers' are in 1000s of bytes per second processed. 64B Bytes = 27056.32k 256 Bytes = 28244.65k 1024 Bytes = 28558.34k 8192 Bytes = 28639.23k With Cryptodev =========== The 'numbers' are in 1000s of bytes per second processed. 64B Bytes = 77508.52k 256 Bytes = 428194.13k 1024 Bytes = 1285770.97k 8192 Bytes = 32507084.80k *2. Openssl encryption test with and without HW* I tried running this openssl command on my box: date ; cat bigfile | openssl enc -e -aes-128-cbc -bufsize 8192 -pass pass:testing123 > /dev/null ; date where 'bigfile' is some large file of > 2 GB in size. Then i rerun it using date ; cat bigfile | openssl enc *-engine cryptodev* -e -aes-128-cbc -bufsize 8192 -pass pass:testing123 > /dev/null ; date and compare the results of the dates of 'before' and 'after'. Below are the results i got. *Without HW it takes 4secs only. **with cryptodev it takes 3min 15 secs* Looks like in *first case cryptodev is increasing the performance but in second case it is decreasing it.* If some body knows this issue,can you please point me to the source code path where i can tweak something to improve performance with cryptodev case. I am using below versions of the sources. *OpenSSL 1.0.1g 7 Apr 2014* *Cryptodev 1.6 version* Please help me on this.
