> The cost of logging the fetch completed statement is dominated by two main factors 1) Formatting the download rate and 2) Minor String concatenation that isn't getting optimized.
> In this jira I propose a new Formatter that is optimized by implementing the StringBuilder#append(long) algorithm, but allows for formatting and reuse of StringBuilder.
