python - Adding a large .shp file to a Streamlit app - Stack Overflow

I am trying to add a large .shp file to a streamlit folium map, and there is a significant lag each time I zoom or re-center the map. The shapefile is large, with about 10000 rows with polygon geometries covering texas and new mexico. I've tried putting it inside a form, and that is helpful, but I still get a long wait time after pushing the submit button.

My question, is there a more efficient way to load a layer than what I have below? I've seen other Streamlit apps with very complex base maps that render almost instantly, and I'm hoping to get the same result. Ultimately, I'd like to add some dynamic drawing features to this, but I can't get to that step until the base map is running well.

import streamlit as st
import geopandas as gpd
import folium
from streamlit_folium import st_folium

st.set_page_config(layout="wide")  

@st.cache_data
def load_shp():
    shp_df = gpd.read_file('testlayer.shp')
    return shp_df.to_json()

layer_to_add = load_shp()
with st.form(key='mymap'):
    m = folium.Map(location = [31.5943, -102.8927], zoom_start = 12)
    folium.GeoJson(layer_to_add, name="my layer",style_function=lambda feature:      {"fillColor": "yellow", "color": "black", "weight": 0.5, "fillOpacity": 0.4}).add_to(m)

    st_folium(m, height = 1000, use_container_width = True, key = 'map')

    submit_button = st.form_submit_button("Submit")
