Fast datetimes in MongoDB
One of the most common complaints about the Perl MongoDB driver is that it tries to be a little too clever. In the current production release of MongoDB.pm (version 0.46.2 as of this writing), all datetime values retrieved by a query are automatically instantiated as DateTime objects.
The next release of MongoDB.pm will fix this problem, allowing for nearly tenfold speed increases under some circumstances. The details are available on my blog here: Fast datetimes In MongoDB.

Why DateTime::Tiny and not something core like Time::Piece?
Time::Piece is definitely a possibility. The only difficult part is that the code that deserializes the returned datetime data from MongoDB is all written in C, so adding support for other date/time modules takes a bit of work.
But if enough people want Time::Piece, I will happily add it.
