        if (disableIOThrottle) {
            cms.disableAutoIOThrottle();
        }
        return cms;
    } else {
        // Gives better repeatability because if you use CMS, the order in which the merges complete can impact how the merge policy later
        // picks merges so you can easily get a very different index structure when you are comparing two indices:
        return new SerialMergeScheduler();
    }
}
