12.Make a symbolic link to the /usr/lib64/openssl/engines/libibmca.so file:
# cd /usr/lib64
# ln -s openssl/engines/libibmca.so
# ls -l libibmca.so
lrwxrwxrwx. 1 root root 27 Oct 20 16:47 libibmca.so ->
openssl/engines/libibmca.so
13.Rerun the same scp commands:
# time scp -c 3des-cbc /tmp/testdata.txt localhost:/dev/null
Password:

# time scp -c aes128-cbc /tmp/testdata.txt localhost:/dev/null
Password:

14.Delete the test file:
# rm /tmp/testdata.txt
You should see an improved througput.
