Yes; our Git server already can't cope with its current load, https://savannah.gnu.org/support/?110712 If some web pages migrate to Git, the load will increase. Then we should get new hardware that is capable, no matter if web pages are using git or not. CCing sysadmin@ and rms@ who can maybe do something about it.
