Hi Joakim,
First profiling show that we cannot easy improve here.
99% of time is just system function READ.
Reason of that?
It needs investigate
1) I want compare on mac intel
2) may be this is result of defragmentation of index pages
* we can try write that DEFRAGMENT also work for index files.
and see if this helps.
3) we can try implement some prediction-algorithms to pre-load index pages
into cache ... Here also not 5 minutes, because it needs count for case of
big db and index not fit cache size...
