CurveIx vs. Linear Scan (cont)

If we assume that each curve lookup involves 3-4 page access (i.e. Tsel=3), we can restate (1) as:

    (1)   (3m+Nf)TP   <   NPTP

Some observations, given NP = 0.05 N:

  • we can't afford to have too many curves   (m)

  • CurveIx has to do effective filtering   (f)

  • clustering can reduce the NfTP term

Difficult to analyse further, so we implemented the system to see how it performed ...
