--- Comment #1 from Frank Ch. Eigler <fche at redhat dot com> ---
Unfortunately, we're not aware of an easy way around this.  There is no way to
seek in the compressed files to an arbitrary index, so one is stuck reading
from the beginning to the file of interest.

I think that, unless the kernel packaging changes, one needs to rely on
(trigger!) debuginfod to fetch & cache highly likely files such as the vdso*. 
Some work is underway to allow this automation, but until then, make sure your
debuginfod server has a large enough fdcache, and you don't groom too
frequently (which clears out the fdcache).
