Slow performance with TextSymbol renderer

[ThomasDale]

I'm experiencing a severe lag with rendering 1000 TextSymbols on a FeatureLayer. This seems to only be a problem in 4.x, but in 3.x, it renders lightning fast. Is there a way to improve its performance?

Hi there, 

Do you have a reproducible case?  I do not see any performance issue here - https://codepen.io/U_B_U/pen/PorLzML?editors=1000

Hi,

Thank you for your response. I found that the bottleneck was occurring in an operation prior to the TextSymbol generation. 

Thanks for taking the time to investigate!
