The numbers certainly don't look convincing, thanks for running the tests.

So I do not think it is wrong to question the usefulness of this feature. 
I'd like to hear Mark's take on this, as prelink-cross is primarily his 
work, he's put a lot of effort into it, and I would want to know where 
the benefits are. Note that Red Hat abandoned prelink in 2013, and 
prelink-cross likewise hasn't seen any commits for two years.
Mark and I did briefly talk yesterday and whilst Mark can/will speak
up, the summary was "drop it".

What makes me sad is that this is an embedded focused feature which 
the project should be caring about, i.e. memory footprint and speed.
I don't know why the numbers don't show it, Mark and I have theories
but it would take work to explore them and neither of us have that time,
nor are we experts on prelink able to maintain it with the time we have
available.

In my view the project should be caring about things like this, instead 
it looks more like a race to look like 'any other desktop distro' and 
drop anything which looks different.

I've tried to say no. Nobody else would appear to care, I'm hearing 
silence. I can't fight this.

Cheers,

Richard
