This category lists all preferences that can be changed to fine-tune performance. Keep in mind that the default values for these preferences are set that way for a reason. Non-default values may cause bugs, reduce performance in other areas, or may only be of benefit to users with certain systems or connection speeds. See each preference's article for details.
