Your task is to solve a 'low' difficulty issue in the gci-leaders repository. Here is the issue:

Issue #27 Reduce number of GitHub API hits

Builds must have been rebased when submitted to GCI.

Lowest build number wins if two participants make the same improvement.

Use "Related to https://github.com/coala/gci-leaders/issues/27" for the last line of your commit message, as your solution will not be the only one.

Do you testing offline, so other participants can not steal your performance idea.

Remember to format your Git Commit Message according to the rules, otherwise the bot will tell you to fix it.
