Performance issue within the UK but fine for US/ CA

Hey all, I have started using cloudflare recently with the addition of APO for woocommerce, the speeds for CA are much faster than the UK where the site is hosted which I’m not too sure why. I have tried preloading fonts and other requests, but the TBT is higher for the UK, once i clear cache and then run a GTMetrix test the TBT is fast like it is for CA, but then additional tests show the higher TBT again, this doesn’t occur for the CA test location. Its got be stumped :frowning:
