Subject [jira] Commented: (LUCENE-1410) PFOR implementation
Date Fri, 03 Oct 2008 21:01:44 GMT


Paul Elschot commented on LUCENE-1410:

I wrote: The number of bits is not really informative, it would be better to have a distribution
of the result of getNumFrameBits(). Then we can see for which nrs of bits loop unrolling might
be tried.

But I misread what was meant by the number of bits, actually the number of frame bits that
I requested is already listed there, so I'll have a go at unrolling for larger numbers of
frame bits, especially for the .prx data.
