Follow the RA, trade speed/inertia for height (and avoid stalling), you're trying to avoid a collision, not to cruise. Generally TCAS are not aware of aircraft performance, though many inhibit climb RA above a certain altitude (check with your outfit). Where that is the case, when 2 level a/c are on collision course, TCAS will generate a descend RA for one and keep the other level.
