Got together with my old dev team (5) who all left the same company at the same time almost two years ago. (Thats a whole other story).

One of them told us he left and went to a new company that measured performance by the amount of commits a dev would to per day. Of course he didn't know that when he signed on.

Three months into the job he had a week where his first commit wasn't until a wednesday and he got called in by the manager to explain his lack of commits and how he was going to improve.

He quit on the spot. Had a new job in less than a week.

Other devs at the company were fixing typo's and just commiting them one at a time to create a lot of commits.

Go for a walk or run outside. Get a fellow dev to play a game on the company xbox. Stop the task and start a new task from the sprint.
