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

[Malte S. Stretz]

The gethostbyaddr* bug might/should (somebody should go and check) be
fixed by unscd, a nscd drop-in replacement which was recently packaged
for Debian and is available in natty.

Title:
  nscd doesn't cache host entries

Status in “eglibc” package in Ubuntu:
  New

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?
