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.

Add p5-B-COW 0.002

B::COW provides some naive additional B helpers to check the COW status of one
SvPV.

A COWed SvPV is sharing its string (the PV) with other SvPVs. It's a (kind of)
Read Only C string, that would be Copied On Write (COW). More than one SV can
share the same PV, but when one PV need to alter it, it would perform a copy of
it, decrease the COWREFCNT counter. One SV can then drop the COW flag when it's
the only one holding a pointer to the PV. The COWREFCNT is stored at the end of
the PV, after the the "\0". That value is limited to 255, when we reach 255, a
new PV would be created,
