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

Try BCP. I'm fairly new to the Microsoft landscape too, but found using BCP really helped with efficiency on loading.

I will try bcp. Somehow, i was convinced I had to have access to the machine running the sql server to use it, but from the doca i see i can specify a remote host.. Will 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.

No, it's a standalone utility that you can download and install separate from SQL Server. It just adds BCP.exe to your command line.

Look for the link that says "Download Microsoft Command Line Utilities 15 for SQL Server (x64)".
