What version of Mercurial were you using? Additionally, was your repository very branchy? Were your pulls stuck for a very long time on 'adding manifests'?

It's possible that your slow pulls were due to the initial storage format being inefficient for very branchy repositories. I've documented migrating to generaldelta to solve this here: https://book.mercurial-scm.org/read/scaling.html#scaling-rep...

Additionally, using the 'clonebundles' feature, it's possible to speed up your initial clone by a huge amount (making it way faster than non-clonebundles Mercurial or Git): https://book.mercurial-scm.org/read/scaling.html#improving-s...

Of course, this is too late for you, I guess...
