@briankardell It appears we use a bloom filter for at least for some CSS rule processing: http://dxr.mozilla.org/mozilla-central/source/layout/style/nsRuleProcessorData.h#72 … /@davidbaron2 replies 0 retweets 0 likes -

@wanderview@briankardell Looks like we don't use bloom filter for QSA, though I'm not sure.@bz_moz would know. Seems fixable.1 reply 0 retweets 0 likes -

@davidbaron@wanderview@briankardell We don't. I tried it once and didn't get a noticeable win, iirc, but we should try measuring again.1 reply 0 retweets 0 likes -

@briankardell @davidbaron @wanderview @SimonSapin Bloom filter adds overhead. Helps more with lots of selectors per element than in QSA.
