Subject Lucene indexing throughput (and Mike's lucenebench charts)
Date Thu, 14 Apr 2016 17:13:44 GMT
Hi,

I was looking at Mike's
http://home.apache.org/~mikemccand/lucenebench/indexing.html secretly
hoping to spot some recent improvements in indexing throughput.... but
instead it looks like:

* indexing throughput hasn't really gone up in the last ~5 years
* indexing was faster in 2014, but then dropped to pre-2014 speed in early
2015
* indexing rate dropped some more in early 2016, and that seems to roughly
correlate to a *big* jump in Young GC in late 2015

Does anyone know what happened in late 2015 that causes that big Young GC
jump?
Or does that big jump just look scary in that chart, but is not actually a
big concern in practice?

Thanks,
Otis
