Lost 3 words out of 12, and not sure of order, mnemonic seed

I lost 3 words out 12 and not sure of the order of the rest besides the first 3, and the last one. I wrote a Python script with mnemonic and the crypto.com wallet library, it works, to my knowledge atleast i still havent found my seed yet, im up to about 70mil combinations the code has processed, but the issue is I wanna see if anyone can make it faster, or just help me in general please.

Code:

import time
import itertools
from itertools import chain,repeat,count,islice
from collections import Counter
from mnemonic import Mnemonic 
import json
from chainlibpy import Wallet
import sqlite3

Words2 = ["2048 mnemonic words"]
count = 0
found = False
mnemo = Mnemonic("english")

#Words I know, just not sure of position
Words2 = ['']

#Words I know
comos = ['word1', 'word2', 'word3']        
def listToString(s):
    listToStr = ' '.join([str(element) for element in s])
    return listToStr

def createdb(address=None, mn=None):

    con = sqlite3.connect("Combos.db")
    cur = con.cursor()
    cur.execute("create table if not exists Addresses (address INT PRIMARY KEY, mnemonic NTEXT)")
    cur.execute("INSERT INTO Addresses (address, mnemonic) VALUES ('{}', '{}')".format(address, mn))
    con.commit()
    con.close()

def checkAddy(phrase):
    global found
    add = "address"
   # testadd = "testaddressnolongerinuse"
    wallet = Wallet(phrase)
    if wallet.address == add:
        createdb(wallet.address, phrase)
        found = True
        print("found")
    
def randomizeWord():
    global count
    global testing
    global comos 
    
    randomw = random.sample(Words, 3)
    words2 = random.sample(Words2, len(Words2))
    comos.extend(words2)
    comos.extend(randomw)  
    comis = ["lastword"]
    comos.extend(comis)
    isValid = mnemo.check(listToString(comos))
    
    if isValid:
        checkAddy(listToString(comos))
    else:
        comos = ['word1', 'word2', 'word3']
    comos = ['word1', 'word2' 'word3']
    count = count +1
    print(str(count))
    
        
while found != True:
    randomizeWord()
