I think this speedup will see people that have big dbs.
We have test on db in 500MB.

* The bigger db, the bigger index files.

1) So there was one wrong-idea which have did linear check.
Now it is disabled. So indexes do Find() several times faster.
In test I have see 8 times speedup. But if db will be 1 Gb, I think speedup
will be even more.

2) and in other place I have improve algorithm to also avoid linear
iteration, this have add yet 30% speedup.

So Indexes now in general 10 times faster.

I think small dbs also can see this improvement if you do a lots of queries.

Obviously that this speedup e.g. Joins...
