hg push getting worse?

[Maurizio Cimadamore]

Hi
I noticed that the time needed for an hg push is getting longer and 
longer. It used to be quite fast when I started using Mercurial (I 
normally work with the langtools repository) - now it takes about 5 
minutes for a push to go through. I first though this was something that 
has to do with the amount of changeset in the hg repo - but this doesn't 
seem to be the case; I also work in the FX compiler and we recently 
switched to mercurial for FX as well - despite the number of changeset 
in FX is greater than the one of the langtools repo, FX pushes are 
really fast (up to 10 seconds).

Could it be jcheck that is slowing down pushes - or some other related 
server-side check?

Thanks
Maurizio
