Lv_textarea_set_text Consume a lot of time

I only use basic functions such as drawing and text area. I use STM32F429IG, and the lvgl version is V7.0.2.
I found that when I use the lv_textarea_set_text(pObj, (char*)tStr) function, such as , when the mcu receives a command,the textarea obj show the string of the command,when i use set lv_textarea_set_text to set some objs(e.g 8) sequencly, the mcu will consume a lot of time(more than 300 ms),how to solve this problem? thanks for your help!

How long is the text you are trying to set? Have you set a maximum length or accepted_chars (these slow down text processing significantly)?
