Very slow slug generation queries with latest BSON and mongo driver about mongoid-slug HOT 3 CLOSED

This makes sense. You should open an issue in bson-ruby against that commit as well, because it's clearly a performance regression.

Then, is there a way to write a test for this in mongoid-slug (eg. examining the query results and making sure it hit an index or the number of documents scanned was 1 when there're 2 records in the DB for example), and then way to modify the query and remove that option in mongoid-slug?

Will do, wasn't sure if I should but I'll file something there and see if anyone has something to add.

I will investigate this, thanks!

As an FYI, I have a branch where I've switched to use Regexp::Raw over Ruby's Regexp to get around the multiline option performance hit.

The former is a class provided by BSON in order to get around this. see mongodb/bson-ruby#71 for that discussion.

I've just commented there mongodb/bson-ruby#71 (comment) . My branch still has 2 failing specs around embedded documents, and I was unsuccessful in debugging that (besides thinking that there might be a further Mongoid issue).

When I get that answered, I should be able to come back here and finish this.
