There is a need to quantify the number of files which will be created when we enable IPA rendering, both to provide an estimate of how much persistent storage is required and to determine what type of load we will place on the TTS / rendering service.
Ideally, we would get numbers for each template on each wiki so we have granular information per wiki and language as well as a total number.
It is possible that we will not capture all the pronunciation templates, so the number we come up with is likely to be a lower bound.
