Subject [jira] [Commented] (OAK-3958) Split SegmentWriter records cache into 2: strings and templates
Date Mon, 01 Feb 2016 07:59:39 GMT

Michael Dürig commented on OAK-3958:
------------------------------------

Hmm I see. The higher load factor trades some memory for CPU cycles. Not sure whether this
is worth it or even notable. Probably not as the write calls are dominated by IO. I guess
we will never know until we benchmark....

> I think it makes sense to split the 2 caches apart, from what I've seen the ratio is
very unbalanced (10 strings to 1 template), so keeping the 2 together might hurt the template
cache.
