I wonder how it takes more than 1.5 hours for checking 200, I have just checked with 300 records and returned back to me within 9 secs.
If possible Can you please provide with your code where it takes so long time? I would like to try this for any better solution for your purpose, but I implemented this for many times and I dont have any performance issue so far.
