Git clone from Gerrit is hanging on 'Cloning into'

Question

I got a ssh clone url from Gerrit website.

git clone "ssh://username@server:29418/code-repo"

But it's really slow and hang on for quite a while on 'Cloning into xxx'.

Why Gerrit is hanging on cloning into ... ?

This is fixed by running GC. I do not know why.
