如何减少Python Firebase Admin SDK中的SSL开销

我已经使用python中的firebase_adminsdk创建了一个代码来将实时数据更新到firebase中，但是ssl开销使得总下载量相当大。是否有任何方法可以减少ssl开销，并使用python通过firebase实时数据库创建持久连接。

#Import 
import xlrd
import sched, time

#scheduler
s = sched.scheduler(time.time, time.sleep)

#Firebase admin
import firebase_admin
from firebase_admin import credentials
from firebase_admin import db

cred = credentials.Certificate(r"C:\Users\HP\Desktop\Pythons\Resource\AccountKey.json")

#Initilising Database
firebase_admin.initialize_app(cred, {
    'databaseURL' : 'https://database.firebaseio.com/'
})

#Loop to run every second
def do_something(sc):
    print("Opening excel....")

    #Opening Document
    file_location=r"C:\Users\HP\Desktop\NIFTY 50 Fyers.xlsm"
    try:
        workbook=xlrd.open_workbook(file_location)
        print("Opened")

        #Opening first sheet
        sheet=workbook.sheet_by_index(0)
        #Creating stockdictionary
        stockdata={}

        for i in range(1,50):
            stockdata[str(sheet.cell_value(i,0))]=sheet.cell_value(i,1)

        #Writing data into firebase database    
        db.reference("Live Data/N50 Stocks").update(stockdata)

        #Display Result
        print("Stock Data Updated")


        indicesdata={}
        for j in range(74,100):
            indicesdata[str(sheet.cell_value(j,0))]=sheet.cell_value(j,1)

        #Writing data into firebase database    
        db.reference("Live Data/Indices").update(indicesdata)

        #Display Result
        print("Indices Data Updated")

        #Opening second sheet
        sheet=workbook.sheet_by_index(1)

        optionsdata={}
        for k in range(2,41):
            optionsdata[str(sheet.cell_value(k,0))]=sheet.cell_value(k,2)

        #Writing data into firebase database    
        db.reference("Live Data/Options").update(optionsdata)

        #Display Result
        print("Option Data Updated")


        #All data finished
        print("____________")

    except Exception:
        print("*********Exception Occured**********")
        #Calling Loop Again
        #s.enter(1, 1, do_something, (sc,))
        pass

    #Calling Loop Again
    s.enter(1, 1, do_something, (sc,))

#Repeat
s.enter(1, 1, do_something, (s,))
s.run()

此连接应持续8小时，firebase ssl开销减少方法很难确定，有谁能缩短此代码以避免ssl开销，并使与firebase的数据连接平滑，使用更少的数据下载
