Thanks, Neale! The gzip and zlib improvements are particularly impressive.

As a quick example of the effect of hardware compression I created a 728M file
filled with random data from /dev/urandom:
Without hardware assist:
# time gzip -c -1 /tmp/gzip.in >/tmp/gzip.out.gz
real 0m35.471s
user 0m25.735s
sys 0m0.846s
With hardware assist:
time ./gzip -c -1
Among the recent additions to EPEL this week include these:
cmake3-3.17.2-1.el7
gzip-1.10-3.68.el7
multiwatch-1.0.0-3.el7
ninja-build-1.7.2-4.el7
node-12.17.0-1.el7
zlib-1.2.11-21.el7
Note, gzip and zlib have support for the z15 compression hardware assist
operations.
