Should I Normalize My Data for Host Ranking?

[xeon123]

I have 2 measures that I am using to rank terms that I get them by prediction (using linear regression). They are the time to transmit X bytes and the time to compute the X bytes. I do the prediction if I execute in host A, B, and C. I add the 2 measures and rank the hosts. I think adding these 2 measures are not enough. Should I normalize these 2 measures?

It depends what decision will be based on the result. You need a cost function which tells you how much weight to give to each measure.
