импорт из репозиториев Perforce и отправка в них (Import from and submit to Perforce repositories)
Представление (Performance)
The fast-import mechanism used by git p4 creates one pack file
for each invocation of git p4 sync. Normally, Git garbage
compression (git-gc(1)) automatically compresses these to fewer
pack files, but explicit invocation of git repack -adf may
improve performance.
