# bcrypt and qpress seem slower than I would expect.... Advice?

ContributorCurrent User Role Beginner
I have a large database I am decrypting and decompressing from a full innobackupex command. I am using the script below to do this. Any suggestions on how to make this go faster, did I miss any 'speed-up' options on either of these commands?

This is on centos 6.9, mysql 5.7 and percona-xtrabackup-2.4. The machine has lots of 8 CPU and 60GB of memory. The disks are SSD with a 20MB/second advertised write read/write rate (This is an AWS r2.x4large machine), incase that matters.
