I have a quad-core MacBook Pro (8 threads total) and once a week I am forced to wait about 5-7 minutes while the entire system becomes effectively unresponsive. Multi-tasking is basically unavailable at this time.

git tells me it is using 8 threads. How do I tell it to use less than that?

Set the pack.threads configuration option to a value between 1 and 7, inclusive.

For example, if you wanted git to use 6 threads instead of 8:

git config --global pack.threads "6"

Alternatively, edit the .gitconfig:

    threads = 6
