I did, and cannot confirm it. It seems that single quotes are *sometimes*
faster in Explorer Windows (roughly 1/3 of my tests did show a faster
response time), but if Mozilla shows a difference at all, it handles double
quotes slightly faster. I found no difference at all in Opera.
I cannot say that these experiments confirm the 15% claim.
