Create a new package glibc-benchtests with the benchmark binaries that
one may download and run to benchmark glibc for their machine. More
importantly, the glibc-bench-compare and bench.mk scripts can run
benchmarks and compare performance of two arbitrary glibc versions as
long as both versions have the glibc-benchtests package.
Usage:
Scenario 1: Compare two build numbers, e.g.:
/usr/libexec/glibc-benchtests/glibc-bench-compare 2.20-1.fc21 2.21.90-11.fc22
If a second build is omitted, comparison is done with the currently
installed glibc.
Scenario 2: Compare two downloaded rpms - only glibc, glibc-benchtests
and glibc-common are needed for both versions. e.g.:
/usr/libexec/glibc-benchtests/glibc-bench-compare -p <dir1> <dir2>
