  We study the Rouquier dimension of wrapped Fukaya categories of Liouville
manifolds and pairs, and apply this invariant to various problems in algebraic
and symplectic geometry.
  On the algebro-geometric side, we introduce a new method based on symplectic
flexibility and mirror symmetry to bound the Rouquier dimension of derived
categories of coherent sheaves on certain complex algebraic varieties and
stacks. These bounds are sharp in dimension at most $3$. As a result, we
resolve a well-known conjecture of Orlov for a large class of new examples,
including all toric $3$-folds and certain log Calabi--Yau surfaces.
  On the symplectic side, we study various quantitative questions such as: (1)
given a Weinstein manifold, what is the minimal number of intersection points
between the skeleton and its image under a generic compactly-supported
Hamiltonian diffeomorphism? (2) what is the minimal number of critical points
of a Lefschetz fibration on a Liouville manifold with Weinstein fibers? We give
lower bounds for these quantities which are to our knowledge the first to go
beyond the basic flexible/rigid dichotomy.
