Hello, We put all our customers in the same core/collection because of this, it is not practical to manage hundreds of cores, including their small overhead. Although it can be advantageous when it comes to relevance tuning, no skewed statistics because of other customers.
In your case, an unused core is probably slow because it is not in cached memory anymore, and/or it has to load from a slow drive. With regards to the locales, i would probably separate the cores by topic only, and have different languages share the same collection/core.
