Whenever the git plugin checks for changes, it runs git rev-parse for every tag in a repository. We have a hundred jobs or so, all of which have many tags. This causes the check for new changes to take longer than a minute. Our builds are configured to check for changes every minute. The net result is that Jenkins is spending all its time/CPU checking for changes.

We upgraded to the latest version of each plugin yesterday. I don't remember what version we were at.

Here is our Git polling log output:

I've attached a screenshot of the job's Git settings.

I've tried leaving the "branch" field blank and using refs/heads/**. Same result.
