update-apt-xapian-index is painfully slow with compressed indexes

[Martin Pitt]

Binary package hint: apt-xapian-index

When enabling compressed apt indexes, update-apt-xapian-index takes ages, presumably because it accesses all individual package records from the lists themselves (not just from the binary pkgcache).

[Martin Pitt (pitti)]

This gets mitigated by disabling compressed apt index by default again for now. It's easy enough to reenable locally for reproducing the bug, so lowering the severity.

apt (0.8.9ubuntu4) natty; urgency=low

  * cmdline/apt-key:
    - set timeout of wget for net-update to 90 seconds (thanks to \sh)

  [ Martin Pitt ]
  * Revert r1819 and r1820 to disable compressed indexes by default again.
    Testing has brought up a few places where this seriously degrades
    performance, mostly in applications which iterate through all available
    package records, like update-apt-xapian-index or synaptic. See
