Hi Alan, thanks for pointing me at the old discussion .

talks about performance benefits . Are you aware of some benchmarks that
showed the improvements ?
If you can find the mails that references the Intel IPP library then you
might have links to performance data comparing the different
implementations. There is also mails somewhere in the archive with a
proposal or patch to have the JDK select an alternative implementation
at run-time, equivalent to LD_PRELOAD. I think we ended up with the
right default.
In reality, if you have the latest distro versions you might be lucky and you
have a nice recent zlib 1.2.11 .
However on older distros , you run in reality into older zlibs (often I see
1.2.8). I don't think that this is a very good status .
Sure but the opposite can arise too, say where someone is using a JDK
release that bundles an older version of zlib.
I agree with the comment that the building instructions need to be
sync'ed up.
