created 2 prs for this bug ... one to echart repo which adds the test case for optimization : https://github.com/apache/echarts/pull/21339 and one which changes the zrender logic of refresh https://github.com/ecomfe/zrender/pull/1142

I didn't feel the perfomance issue (probably because I'm using a M5 MacBook so I cannot feel it. You should probably create another series with the same amount of labels but different series type to test if this is a problem with geo.
