Hi,

i am runningthis command

git filter-branch --env-filter 'export 
GIT_COMMITTER_EMAIL="$GIT_AUTHOR_EMAIL" 
GIT_COMMITTER_NAME="$GIT_AUTHOR_NAME" 
GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"' --prune-empty --tag-name-filter 
cat -- --all


in a repository which i copied to /dev/shm before. According to "top", 
the git process only consumes about 5 percent of the CPU. The load is 
between 0.70 and 1.00.

I assume that there is a lot of process forking going on. Could that be 
the cause?

Any ideas how to further improve?

Best regards
Henning
