I asked Dimitri about this on IRC. He isn't expecting to work on this,
and nor is the server team. We think the security team will take this on
according to their priorities? If this does need the server team's
attention, please let us know.

  In Progress

Bug description:
  There is a known and patched issue with version 2.4 of libseccomp
  where certain operations have a large performance regression. This is
  causing some packages that use libseccomp such as container
  orchestration systems to occasionally time out or otherwise fail under
  certain workloads.

  Please consider porting the patch into the various Ubuntu versions
  that have version 2.4 of libseccomp and into the backports. The
  performance patch from version 2.5 (yet to be released) applies
  cleanly on top of the 2.4 branch of libseccomp.

  For more information, and for a copy of the patch (which can also be
  cherry picked from the upstream libseccomp repos) see the similar
  Debian issue: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=943913
