Python Dash Plotly Websockets

Question

I'm a n00b with Dash and I'm trying to update a DashTable from websocket feeds. The code appears to work when there aren't too many feeds, but once there are, Chrome starts spamming my server with fetch requests (from dash_update_component)

Is there any way to make this more performant ?

import dash_bootstrap_components as dbc
import dash_core_components as dcc
import dash_html_components as html
import json
import pandas as pd

from dash import callback, Dash, dash_table
from dash.dependencies import Input, Output, State
from dash_extensions import WebSocket

symbols = ["BTCUSDT"]
columns = ["symbol", "bid_volume", "bid_price", "ask_volume", "ask_price"]


def create_data():
    data = {}
    for col in columns:
        if col == "symbol":
            data[col] = symbols
        else:
            data[col] = [None] * len(symbols)
    return data


df = pd.DataFrame(data=create_data())

# Create example app.
app = Dash(prevent_initial_callbacks=True)
app.layout = html.Div([
    dash_table.DataTable(df.to_dict('records'), [{"name": i, "id": i} for i in df.columns], id='tbl', editable=True),
    dcc.Input(id="input", autoComplete="off"), html.Div(id="message"),
    WebSocket(url="wss://fstream.binance.com/ws/", id="ws")
])

# Write to websocket.
@app.callback(Output("ws", "send"), [Input("input", "value")])
def send(value):
    sub_msg = {
        "method": "SUBSCRIBE",
        "params": [],
        "id": 1
    }
    for ins in symbols:
        sub_msg["params"] += ([f"{ins.lower()}@bookTicker"])
    return json.dumps(sub_msg, indent=0)


# Read from websocket.
@app.callback(Output('tbl', 'data'), [Input("ws", "message")])
def on_feed(message):
    if "data" not in message:
        return dash.no_update
    else:
        data = json.loads(message["data"])
        print(data)
        symbol = data["s"]
        row_idx = df.index[df['symbol'] == symbol].tolist()[0]
        df.loc[row_idx, columns] = [symbol, data["B"], data["b"], data["a"], data["A"]]
        return df.to_dict('records')
