preferable to just merge them in 1 row using composite col names(instead of
keeping in 3 rows) ? Does this improve read performance, anyway ?

You almost definitely want to merge this row. In spinning disk systems like
SCSI or sata seeking data on disk is at a premium so having 3 independent
seeks for data that is always read together is not good.
