Understanding “um so schneller” in this Kafka sentence?

Question

What is the contribution of *um* and the comparative form of *schnell* to the meaning of this sentence in Kafka’s *Der Verschollene*? >Und da das Ärgste ausgesprochen war, drängte alles andere **um** so schnell**er** nach, er sagte, ohne die geringste Lüge zu gebrauchen, Dinge, an die er gar nicht eigentlich vorher gedacht hatte.

Answer 1

In this sentence, "um so schneller" means "even faster"; "um so" + the comparative form of the adjective means "even". However, if you use it coupled with "desto" in a sentence, e.g. "um so groesser, desto besser", it means "the ....the" ("the bigger, the better").
