Unfortunately, in this instance, it is a live production system, so we
cannot conduct experiments. The number is definitely accurate.

We have many different systems with a similar load that observe the same
performance issue. To my knowledge, the Lucene integration code is
fairly well optimized.
It is possible that the extreme slowness is a combination of factors,
but with a bit of luck it will boil down to a single thing. Standard
procedure it to disable features until it performs well, so

- Disable running updates
No can do.
- Limit page size
Done this.
- Limit lookup of returned fields
Done this.
- Disable highlighting
No highlighting.
- Simpler queries
They are as simple as possible.
- Whatever else you might think of
Our application has been using Lucene for seven years. It has been constantly optimized over that period.

I'll conduct further testing...

At some point along the way I would expect a sharp increase in
performance.

I've requested access to the indexes so that we can perform further testing.
Great.
