In general, code duplication itself has negligible impact on performance
(which can go either way, depending on the circumstances).

Code duplication leads to bugs and increases the cost of development.
Its long-term effect is often exponential. I speculate that at least 20%
of Squid bugs are caused by code duplication, and an average Squid
development project is at least 20% more expensive because of it. It is
a big deal!

Fortunately, it is usually easy to avoid when writing new code.
Unfortunately, I have to keep begging and begging to avoid it in new
code, as if it is some obscure or unimportant problem and not a basic
development principle.
