Performance concerns may have been related to the use case of importing
Subversion history into git.
It is certainly faster to create a dump file over the network, rather
than syncing the repository and creating a dump files from that in a
second step.

Not sure if that is what people were talking about though.
Do you have a link to related discussion in the archives?
