When GOROOT is not set as an environment variable, GetBuildContext fetches it from 'go env GOROOT', which takes about 50ms on my machine. This overhead can almost double the time it takes to run an update since GetBuildContext is called relatively frequently. Instead, read GOROOT during initialization and cache it for GetBuildContext.
