Narrative:

Air carrier X was at FL330 from mol southeast to fak. Uga Y (a learjet) was climbing out of FL340 to FL390. I noticed the lear was not climbing very good. I told air carrier X to descend to FL290 then told the lear to expedite climb. Then turned the air carrier X and he asked if he was given a descent clearance.
