OLEDB command in SSIS

I AM working on DW building and i m using SSIS.I haev problem with data transformation OLEDB command.I have written a query to clean data in OLEDB command box ,but it takes whole lot of time because at a time it slects 6000 rows from the source and put in to destination but i have 300000 rows to process.How can i increase the size.The OLE DB command executes for every row in the data flow. Are you sure you're stating the correct component?

You should use an OLE DB Source component hooked to an OLE DB Destination component to move your data.|||I want to delete some data while transfering from one to another i.e i want to do cleaning.|||If you want this to be fast, try writing the keys for the rows to delete to a temporary table, then use an Execute SQL task to issue a batch DELETE statement. Since the OLEDB Command transform executes once for each row that passes through it, it will be slower than doing a batch.
