Jesus. It works for me. After disable writebitmap, time cost decrease

But now it turns out that, remote side takes 13 seconds to receive the
pack,  since git receive-pack is triggered automatically from remote
side, is there anyway to enable GIT_TRACE2_PERF on server side?

For the environment variable, it depends on your protocol. If you can
push over ssh (and the other side lets you execute arbitrary commands),
then:

  git push --receive-pack='GIT_TRACE2_PERF=/tmp/foo.trace git-receive-pack'

Otherwise, you can look at setting the trace2.perfTarget config option
on the server side. I haven't played with it myself before.
