Lag Often After Data SPlit

Good day
Big thumbs up for all dev who contribute into ffxiv, bless you all. Amen
I have one problem on the game, the game would work fine on normal world and the game would lag in duty quite often now but I know it will happen but I feel like after the data split my game would lag on duty quite often, and I even change internet for this,but still lag on duty, I play tank a lot and cuz of this I kept getting kicked cuz the game would lag hard and stop the game,I've only played this for a year but since the data split my game would lag
i would love to hear from the team if there any concern on the server
I'm on chaos DC on Moogle

Thank you and best regards

Thank you for posting in the Final Fantasy XIV Technical Support Forums.

How long have you been experiencing lag issues? Have any changes to the network been made? How are you connecting to the internet ( WIFI or Ethernet cable)? What was tried to alleviate the problem?

Hope to see you online!
