Narrative:

On walk around in ZZZ for next flight; ramp person asked if there was any problems with weights moving during our flight. Told him not one that I was aware of. Apparently; ZZZ1 ramp personnel had not secured either cargo hold; and all bins and pallets were not locked in position properly and had shifted and moved during our landing or takeoff. 6 of them weighed over 6;000 pounds; and 1 weighed over 10;000 pounds according to the ramp personnel. They had to unload and reload all the bins correctly prior to our next flight. Talking with the captain during our next leg; he commented that he felt the aircraft was sluggish coming off the ground on rotation; and mentioned that attitude during approach seemed a little 'different' than normal. There never appeared to be problems controling the aircraft; and other than being told on the ground in ZZZ; I don't think we would have ever known about this issue. One other thing; the ramp supervisor in ZZZ1 did mention to us that they were having trouble loading some bins; but that was all that was said; and did not give it a second thought until we landed in ZZZ and were questioned by the ramp personnel there. They said that this is an ongoing problem with aircraft coming in from ZZZ1.

TALKING WITH THE CAPT DURING OUR NEXT LEG; HE COMMENTED THAT HE FELT THE ACFT WAS SLUGGISH COMING OFF THE GND ON ROTATION; AND MENTIONED THAT ATTITUDE DURING APCH SEEMED A LITTLE 'DIFFERENT' THAN NORMAL. THERE NEVER APPEARED TO BE PROBS CTLING THE ACFT; AND OTHER THAN BEING TOLD ON THE GND IN ZZZ; I DON'T THINK WE WOULD HAVE EVER KNOWN ABOUT THIS ISSUE. ONE OTHER THING; THE RAMP SUPVR IN ZZZ1 DID MENTION TO US THAT THEY WERE HAVING TROUBLE LOADING SOME BINS; BUT THAT WAS ALL THAT WAS SAID; AND DID NOT GIVE IT A SECOND THOUGHT UNTIL WE LANDED IN ZZZ AND WERE QUESTIONED BY THE RAMP PERSONNEL THERE.
