Thread:Extension talk:Scribunto/Big table vs several smaller tables

Following the advice at mw.loadData I have created a table of flags w:Module:Sandbox/QuimGil/FlagMaster keeping it separated from the module that knows how to deal with them: w:Module:Sandbox/QuimGil/Flags. Now, I have a doubt: should I bother about splitting the big table into smaller ones, with the risk of having to load more than one table while searching for the right flag? Is there a significant difference in milliseconds doing it in one way or another?
