I miss an else statment here, or maybe

 while my $line(@lines1) {
        @words = split (/\,/, $line,8);            
        next if $words[6] <= 90; ...

Foreach requires typically more memory than while (and you have several foreach loops), use while instead unless you have good reasons to use a foreach loop

I am usign hashkeys to first put one file into the hash. And then search the specific text.

If you have a lot of files and you expect a lot of non matching lines try to discard these undesired files/lines as soon as possible. Sounds to me like a work for grep, regexp and next

You could want not to care for what's after the seventh field, if this is your case, put a max num of fields in split. Thus split should end before and require less memory.
