Narrative:

Climbing out of rsw and on ZJX, controller seemed overloaded by a 30 mi in trail limitation for ord. We made numerous turns as much as 90 degrees off course and slowed T0 .75 mach. Climbing through FL315, we were told to 'level off at FL310.' we informed him that we would be descending back to FL310 which we did expeditiously. We were then given a continued climb to FL390 on a heading of 280 degrees. Climbing through FL365, we were told to descend 'immediately' to FL350 and turn immediately to 040 degrees. We pushed the nose over and were level at FL350 in less than 30 seconds. We watched an air carrier Y aircraft go over the top of us at FL370. We got a 'traffic, traffic' callout from the TCASII, but no RA. After this last series of maneuvers, I told the controller that I wished they would get their act together down there, or some words to that effect. He replied that they were working on it, or some words to that effect. There was some significant problems going on at ZJX and the controller was not on top of the situation. I do not believe there was any loss of separation or anything that I would classify as an near midair collision, but there was significant concern on the part of our passenger and crew due to the unnecessary and relatively pronounced maneuvering. Upon landing, I called and spoke to both the shift supervisor and facility manager at jax. They said their quality assurance department would be reviewing the incident.

Title: 30 MI IN TRAIL FLOW PUT IN FOR ORD CAUSED SECTOR OVERLOAD AT ZJX.

Narrative: CLBING OUT OF RSW AND ON ZJX, CTLR SEEMED OVERLOADED BY A 30 MI IN TRAIL LIMITATION FOR ORD. WE MADE NUMEROUS TURNS AS MUCH AS 90 DEGS OFF COURSE AND SLOWED T0 .75 MACH. CLBING THROUGH FL315, WE WERE TOLD TO 'LEVEL OFF AT FL310.' WE INFORMED HIM THAT WE WOULD BE DSNDING BACK TO FL310 WHICH WE DID EXPEDITIOUSLY. WE WERE THEN GIVEN A CONTINUED CLB TO FL390 ON A HDG OF 280 DEGS. CLBING THROUGH FL365, WE WERE TOLD TO DSND 'IMMEDIATELY' TO FL350 AND TURN IMMEDIATELY TO 040 DEGS. WE PUSHED THE NOSE OVER AND WERE LEVEL AT FL350 IN LESS THAN 30 SECONDS. WE WATCHED AN ACR Y ACFT GO OVER THE TOP OF US AT FL370. WE GOT A 'TFC, TFC' CALLOUT FROM THE TCASII, BUT NO RA. AFTER THIS LAST SERIES OF MANEUVERS, I TOLD THE CTLR THAT I WISHED THEY WOULD GET THEIR ACT TOGETHER DOWN THERE, OR SOME WORDS TO THAT EFFECT. HE REPLIED THAT THEY WERE WORKING ON IT, OR SOME WORDS TO THAT EFFECT. THERE WAS SOME SIGNIFICANT PROBS GOING ON AT ZJX AND THE CTLR WAS NOT ON TOP OF THE SIT. I DO NOT BELIEVE THERE WAS ANY LOSS OF SEPARATION OR ANYTHING THAT I WOULD CLASSIFY AS AN NMAC, BUT THERE WAS SIGNIFICANT CONCERN ON THE PART OF OUR PAX AND CREW DUE TO THE UNNECESSARY AND RELATIVELY PRONOUNCED MANEUVERING. UPON LNDG, I CALLED AND SPOKE TO BOTH THE SHIFT SUPVR AND FACILITY MGR AT JAX. THEY SAID THEIR QUALITY ASSURANCE DEPT WOULD BE REVIEWING THE INCIDENT.
