Omg it's sooo daammmn slooow it takes around 30 seconds to bulk - insert 15000 rows

Disabling indices doesn't help. Database log is at SIMPLE. My table is 50 columns wide, and from what i understand the main reason is the stupid limit of 2100 parameters in query in ODBC driver. I am using the . NET SqlBulkCopy. I only open the connection + transaction once per ~15000 inserts

I have 50 millions rows to insert, it takes literally days, please send help, i can fucking write with a pen and paper faster than damned Microsoft driver inserts rows

What is your latency? Can you move data closer to where db is (cloud)? Did you change isolation level? Or recovery model? Did you try bcp? Any indexes you have in table should be deleted?

Will try bcp & report back EDIT: I can't install bcp because it is only distributed with SQLServer itself, and I cannot install it on my corporate laptop.
