Fastest way to compare two sheets and copy matches

Hello, im having some trouble comparing equal values between two sheets. I need to search a sheet, find a value, compare to another one and if found on the other one, copy to a new sheet. Ive found a few codes that search the sheets but they are very slow.. so whats the fastest? I have around 60k rows to search on a column and 5k to search on the other. Another thing apart, how do i find the word "function" and create a copy range from there on until the last populated row? Thank you

Please post a sample workbook.

There. The thing i mentioned is to compare sheet 2 with sheet 1 returning to sheet 3 the exact values of sheet 2 found on sheet 1. But row by row takes too long. Thank you
