This is the fastest encode/decode I have been able to find as standard packages:

dd if=/dev/zero bs=1000k count=1k 2>/dev/null |
  perl -MMIME::Base64 -0777 -e 'while(read(STDIN,$buf,60*57*12)){print
encode_base64($buf)}' |
  perl -MMIME::Base64 -e 'while(read(STDIN,$buf,770*50)){print
decode_base64($buf)}' |
  dd bs=1000k >/dev/null

I am surprised it is so slow (encode 200 MB/s, decode 100 MB/s), and
that there are no C/C++ packages that are faster.
