Yiorgos,

Could you confirm that performance degradation was not related to TABLEUPDATE, but to SQL-UPDATE called in the scan loop?
Could you please do it on both threads so people will know where the real problem is.

Thank you,
Aleksey.

P.S. You can simply switch to row buffering to avoid explicit TABLEUPDATE calls in the scan loop.
