bash_completion is too slow because it does strange things: it parses
itself because it wants to emulate the behavior of "-o plusdirs".
See

for a preliminary patch.
Thanks for pointing this out. This would indeed be a significant

Hello,
I ran some benchmarks of Bash 4.0-rc1. It is quite impressive! Here are the
results.
My computer is a Pentium M (running at 600 MHz for the test), running Linux
2.6.26 with libc6 version 2.7 and Debian bash-completion version 20080705.
The figures are averages over 100 tests.

The first public release candidate of bash-4.0 is now available with the URL
ftp://ftp.cwru.edu/pub/bash/bash-4.0-rc1.tar.gz
This tar file does not include the formatted documentation (you
should be able to generate it yourself).
This release fixes the remaining serious bugs in the bash version
