a quick SQL performance question.

Dear all !
I've got a cursor , which selects approximately 25% of records in a table (the total number of records in that table is typically 2 to 20 thousands). For each record ,fetched in that cursor, i need to do some processing , and then delete that record.
Now, what's faster:
1) Add the rowid to the fields selected inside the cursor, and issue "delete from MYTAB where rowid = ...." , for each record inside the cursor. or
2) Leave the cursor intact, and just issue one delete statement afterwards, which will delete all the records , fetched by the cursor.

This operation is executed every couple of seconds, so i want to maximally optimize it .
Cheers.
I'd very much appreciate a prompt responce. Thanks a lot ~
