thanks for replying. currently checking is done on the fly to minimize the waiting time to see an available domain. Since, the results are ranked with good ones on the top, it helps in early engagement as checking all will be slower. I do plan to work towards bulk checking and optimization in future. Filtering by length and extension hacks are great suggestions. Will include them soon.
