Hi, thanks your your sudden enthusiasm of my report. I wrote the script
somewhat 2 years ago now as a proof of concept, and I've never had the
need for spell checking feature in command-not-found. :~)
I will see what I can do to help, though I am a bit stretched for time
these days.
Regards.

I profiled your code (0.2.41ubuntu2) and on my computer the bottleneck is this
statement:
SourcesList()
The slow part of that is that it reads the info files in

While I appreciate your enthusiasm and desire to fix this I have a few
comments:
1) Unless I missed something your implementation always reads the whole
database file, I would rather avoid that.
2) The similar result search you employed is much weaker than the one used by
current implementation,

Also, two warnings:
- I didn't really think about what needs to go in the database. (In other
words, makedb.sh is a complete hack.)
- figuring out the active sources is also a hack, because I was lazy to fugure
out how to use libapt from C; it may be worth using it unless it significan

I checked your script -- it does not seem to offer typo corrections -
could you please add that feature (or disable it in c-n-f) and re-
benchmark both?

Feel free to help me out. The only issue why this app is slow is python
startup time. A rewrite in C would make it much more responsive. NB: The
app is _fast_ but not _responsive_.
More than a year ago I did an experiment with c-n-f running as a daemon
with a trimmed-down C program talking to it o
