Strings are about retraction length. They disappear for me at about 10 mm retraction length.
Retraction speed determines whether there are small blobs of additionally deposited material at the locations where there is a retract (or retract reverse). If you get the blobs then you need to increase the speed. They disappear for me at about 150 mm/s.
