Hi Troy,
Do you have one project that occupies ~2GB of space, or multiple
projects contained in one repository consuming ~2GB of space. I suspect
the later, because we have multiple projects contained in multiple
repositories occupying ~1.7GB and no performance impact. The largest
project is ~120MB.
Maybe you should consider re-organising your repository into smaller
ones. :)
BTW : Were you suggesting that it takes ~6min to checkout the entire
~2GB ?
Thanks
Lakshman
