Mark Miller commented on SOLR-4074:
-----------------------------------

bq. but app developers should always explicitly set it based on their application

My guess is that a large enough group of people take the defaults that it matters. App developers never do what they should :)

> You get diminishing returns after 100, but gains up to 100. In this day and age of RAM, it seems better to default to 100 and have essentially the top indexing speed the buffer can give us.
