[Bug 613662] Re: nscd doesn't cache host entries

[Scott Moser]

The debdiff here looks sane, and acknowledgement that it is carried in
RH and SuSE is valuable.  (Direct links/pointers to patches there would
be nice though).

There was some discussion of it http://irclogs.ubuntu.com/2010/12/14
/%23ubuntu-devel.html .  Main decision was to let it sit for now.

Title:
  nscd doesn't cache host entries

Status in “eglibc” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: nscd

Debian (and by implication Ubuntu) are the only distros to disable nscd hosts caching. In most cases, it is deployed with the expectation to mitigate expensive lookups (eg over VPN).

The bug cited [1] has been rejected by the core glibc developers three years ago as not a bug; all other distros (including Redhat EL and Novell SLES) have this functionality enabled. Why should we continue to penalise Ubuntu's performance any longer, in cases where nscd is deployed to improve performance?
