Turbo workspace timings
If you work within a monorepo and want to get a breakdown of the time that each workspace takes to run a task (lib:build in the below example), then these three shell commands will do that!
```
yarn turbo run lib:build --summarize
SUMMARY_FILE=$(/bin/ls .turbo/runs/*.json | head -n1)
cat $SUMMARY_FILE | jq '[.tasks[] | {"taskId": .taskId, "duration": (.execution.endTime - .execution.startTime)}] | sort_by(-.duration)
```
```
yarn turbo run lib:build --summarize
SUMMARY_FILE=$(/bin/ls .turbo/runs/*.json | head -n1)
cat $SUMMARY_FILE | jq '[.tasks[] | {"taskId": .taskId, "duration": (.execution.endTime - .execution.startTime)}] | sort_by(-.duration)
```
