Why was the website so slow for so long?

The cause of the slowdown was a change to the ZFS dataset. In conjunction with the database server, very little caching was being done. This combination resulted in increased disk I/O as the system churned through the database. Details in the blog post which outlines the various things which changed. Many graphs.

New port: databases/cassandra2

Cassandra is a highly scalable, eventually consistent, distributed,
structured key-value store. Cassandra brings together the distributed
systems technologies from Dynamo and the data model from Google's
BigTable. Like Dynamo, Cassandra is eventually consistent. Like
BigTable, Cassandra provides a ColumnFamily-based data model richer
than typical key/value systems.

Cassandra was open sourced by Facebook in 2008, where it was designed
by one of the authors of Amazon's Dynamo. In a lot of ways you can
think of Cassandra as Dynamo 2.0. Cassandra is in production use at
Facebook but is still under heavy development.

The previous version is still available as databases/cassandra.
