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.

net/owamp: Unconditionally define a private timespecadd

net/owamp assumes that if timespecadd is defined, it's identical
to the two-argument version found in the FreeBSD kernel.  However,
the three argument version found in NetBSD and OpenBSD is actually
more common.  An upcoming commit to head will replace FreeBSD's
version with the NetBSD version.  So net/owamp shouldn't assume
that if FreeBSD defines timespecadd, it's defining the 2-argument

OWAMP is a command line client application and a policy daemon used
to determine one way latencies between hosts. It is an implementation
of the OWAMP protocol as defined by (When referring to the
protocol within this document, "OWAMP" will be in italicized. In
all other instances, "OWAMP" will be referring to this implementation.)

With roundtrip-based measurements, it is hard to isolate the direction
in which congestion is experienced. One-way measurements solve this
problem and make the direction of congestion immediately apparent.
Since traffic can be asymmetric at many sites that are primarily
producers or consumers of data, this allows for more informative
measurements. One-way measurements allow the user to better isolate
the effects of specific parts of a network on the treatment of
