If you are using the q parameter, the score is being calculated in any case, and while we have never measured this, I would imagine that the performance hit from retrieving the score would be miniscule. Are you perchance thinking of using filter queries using the fq parameter? As filter queries are cached, using these can indeed make a difference. Regards, Gora
