Nicolas,

in case it helps you, here are results from elp-instrument-package for
org for a default agenda view.  My agenda files have >50k lines.

Curiously, org-bullets-mode seems to be the main bottleneck on my system
(Debian testing with 8 core Intel(R) Core(TM) i7-2760QM CPU @ 2.40GHz)

If I remove the org-bullets and org-ellipses customisations, I get:

A > 4× improvement!

Maybe the OP is customising bullets as well...
