[Bug 790043] Re: Bash-completion slows up the start of bash

[Atanas Atanasov]

@Peter: I am most probably misreading your comment about lack of
background execution support in shell scripts. Why can't we load the
completions with ". /etc/bash_completion &" instead of ".
/etc/bash_completion"?

Title:
  Bash-completion slows up the start of bash

Status in bash-completion package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: bash-completion

  I have been noticing that bash has unusually slow start-up times.
  After looking into the problem, I found out this is mostly caused by
  the execution of /etc/bash_completion (calls to this exist in several
  places). Of course, removing them speeds up the start but leaves a
  less functional shell. As a work-around I would like to suggest
  starting up /etc/bash_completion in the background. In this way, bash
  will start quickly, have access only to basic built-in completions for
  the first 2 seconds until /etc/bash_completion finishes executing.
