If you are using mesh{} (as opposed to mesh2{} syntax), this is
"normal": while parsing each additional vector (normal, vertex and so
on) of a mesh(), the parser perform a search on already parsed elements
of same kind.
For 1 million elements, that means 1 million search over an average of
half-million... can be very slow near the end.
Mesh2 syntax is optimised, but harder: it assumed the lookup as already
been done by the user. It is faster (really faster) on large mesh.

Just because nobody complains does not mean all parachutes are perfect.
