We could shut up the alarms, but this makes the machine very slow for
about 4 hours during peak time.

A few ideas to mitigate the issue:
1. schedule the build during night hours (where is this configured?)
2. run the whole thing under nice & ionice (where is it being started?)
3. run 'git gc' periodically (assuming it's a repo fragmentation issue)
