ferment pressure

Hi Guys, Is it true that an increase in brew pressure allows us to ferment at higher temperatures and therefore faster times. Say 1.5 atmospheres
if so why?

I've read that, and I often transfer from my primary to a keg before fermentation is complete. The beer carbonates as it finishes fermenting, which is convenient, and I let the temp rise to ambient. The temp rise is intended to finish the beer more quickly: here's a link to a discussion of an accelerated fermentation process for lagers:

I have no idea if pressurization plays a part.
