Hi all, Using PhpMyAdmin, I seldom get the warning message: PRIMARY and INDEX keys should not both be set for column `ID`
I understand its meaning, but I was wondering to what extent having a field indexed AND being a primary key might slow down/speed up my queries. Is that gonna take twice the time if I am searching on the ID field, just because there are two indexes? I'd like to have a rough idea of how serioulsy I need to avoid these.
