Narrative:

The BE40 was at FL290 and requesting FL370. Traffic was observed at FL350, so I climbed the BE40 to FL330. Several other sits requiring separation were ongoing at this time and required my attention. Approximately 2 mins after the climb to FL290 was issued, I noticed the BE40 had only reached FL300. I idented that it was in conflict with a B737 at FL310 opposite direction at 15 mi. I issued a vector of 060 to the BE40. Pilot read back 020 degrees. I reissued 060 degrees. I then issued a 270 degree heading to the B737. The B737 executed a prompt and efficient turn. The BE40 barely turned within the first 30 seconds of the clearance. I feel that the non standard rate of climb by the BE40 and poor response by the pilot to ATC clearance were the main factors in this event.

Title: ZJX CTLR EXPERIENCED TFC CONFLICT WITH CLBING ACFT AT FL310.

Narrative: THE BE40 WAS AT FL290 AND REQUESTING FL370. TFC WAS OBSERVED AT FL350, SO I CLBED THE BE40 TO FL330. SEVERAL OTHER SITS REQUIRING SEPARATION WERE ONGOING AT THIS TIME AND REQUIRED MY ATTN. APPROX 2 MINS AFTER THE CLB TO FL290 WAS ISSUED, I NOTICED THE BE40 HAD ONLY REACHED FL300. I IDENTED THAT IT WAS IN CONFLICT WITH A B737 AT FL310 OPPOSITE DIRECTION AT 15 MI. I ISSUED A VECTOR OF 060 TO THE BE40. PLT READ BACK 020 DEGS. I REISSUED 060 DEGS. I THEN ISSUED A 270 DEG HDG TO THE B737. THE B737 EXECUTED A PROMPT AND EFFICIENT TURN. THE BE40 BARELY TURNED WITHIN THE FIRST 30 SECONDS OF THE CLRNC. I FEEL THAT THE NON STANDARD RATE OF CLB BY THE BE40 AND POOR RESPONSE BY THE PLT TO ATC CLRNC WERE THE MAIN FACTORS IN THIS EVENT.
