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

Do you have any measurements on how long it takes when you just 'do it raw'? Like trying to do the same insert though SQL Server Management Studio or something?

Because to me it's not really clear what's slow. Like you're complaining specifically about the Microsoft ODBC driver - but do you base that on anything? Can you insert faster from Linux or through other means?

Like if it's just 'always slow' it might just be the SQL Server. If you can better pinpoint when it's slow, and when it's fast(er) that probably helps to tell how to speed it up
