Compare Columns in two files

Hi all,

I would like to compare a column in one file to a column in another file and when there is a match it prints the first column and the corresponding second column. Example

File1
ABA
ABC
ABE
ABF

File 2
ABA 123
ABB 124
ABD 125
ABC 126

So what I would like printed to a file is
ABA 123
ABC 126

The only thing is that in file 1 there are 8,000 columns while in file 2 there are 140,000 columns to search for. I have tried grep -f but it doesn't work or is very slow?

Any quick solutions?

Thanks
