In short, we could not distinguish the performance gains of prelink over the "background noise" in many (or even most) cases. So, I was wondering if you are aware of any use-cases where prelink provides measurable benefits. In would be awesome if you could run "unSPEC" on your systems and report back the numbers.
Please take prelink behind the barn and shoot it. Thanks. Every year people point out how obsoleted it is, yet we can't get seem to rid of it. The amount of time I've wasted on prelink in combination with FIPS is something another decade of prelink speed gains isn't going to compensate me for. I think /etc/prelink.conf.d along with the cron job and its sysconfig override is an overengineered solution (and ugly because any blacklist package has to own the directory of prelink too) How can we have this discussion? We have had reports of numbers showing no real gain. We know it affects ASLR negatively and complicates FIPS engineering. Why haven't we at least reached a compromise where prelink is _optional_ and not installed per default?
