my experience was that the second went faster. DD1s birth was 9.5 hours and DD2s birth was 2.15 hours.

BUT i reckon DD1s birth was slowed due to being given pethidine and having to lie on my back for pushing and basically not feeling very safe or supported in my environment. The second birth was carefully planned to have a selected team of 'support' where i handpicked my midwives etc and ensured to put into place everything that i felt i needed to feel safe and supported. so i believe that the labour was able to flow naturally and with ease and in its own time...

HTH big hugs have everything crossed that you get your dream birth experience!
