Summary: We describe a modification to the well-known large prime variant of the multiple polynomial quadratic sieve factoring algorithm [Eurocrypt '90, Lect. Notes Comput. Sci. 473, 72--82 (1991; Zbl 0779.11061)]. In practice this leads to a speed-up factor of 2 to 2.5. We discuss several implementation-related aspects, and we include some examples. Our new variation is also of practical importance for the number field sieve factoring algorithm.
