Thanks Riku. Although it's impossible to draw conclusions from this trace
snippet since you didn't include the STAT lines (so it could actually be
performing a FTS or FFS for all we know), we can give you the benefit of the
doubt since Christian has shown us a test case with all the details.
My guess is that the p3=40 is due to the hiddden parameter setting
_table_lookup_prefetch_size=40
Regards,
Brandon

I had deleted the tracefile, but I did have a script to reproduce the results.
