Yes that is true. We build this tool with easy deployment in mind. And we've devoted a lot of our effort to performance. Just check the linux repository for instance (http://gitplex.pmease.com/demo/linux), GitPlex is able to calculate latest commits of many sub folders quickly, compared to decades needed by other tools, :) If your repository is not as large as linux, a 1 cpu machine with 1G memory allocated to GitPlex will be more than enough.
