Biztalk burying sql server

 I am a DBA on a sql 2005 box which hosts Biztalk.  One of the developers wrote a package/orchestration  (and then left) which is killing my sql server.  It takes a flat file input and compares it to records in an oracle 8 db and then either inserts or updates the record.  When running profielr during this process it created over 400,000 statements like this

exec [dbo].[bts_InsertProperty] @uidBatchID=N'{BF4ED36E-EE93-4C6E-B3A0-E557D9CBC06A}’,@nOrderID=0,@uidMessageID=N'{FC20E08C-B6C4-4810-8704-F0C6E453F5E0}’,@uidPropertyID=N'{A146E00A-4AC1-4926-95E3-37A512B6644F}’,@vtValue=1

The flat file has about 60,000 records.  Is this normal for this type of processing.  The sql server has 32 gig of RAM, but the disk gets killed during this process which takes about 15-20 minutes.
