Before you move on, you may want to expand the skills and techniques you’ve explored in this chapter. Here are some suggestions:

• Execute the tracer on the last version of the tool. Look for the new goroutine pattern. Is there a difference between this version and the previous version? Have you addressed the scheduling contention?
• Improve the colStats tool by adding more functions such as Min and Max, which return the lowest and the largest values in a given column. Write tests for these functions.
• Write benchmarks for the new functions Min and Max.
• Profile the functions Min and Max, looking for improvement areas.
