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

    A friend of a friend found that exporting to csv and importing is the fastest route. Honestly crazy, but I recreated a test and it’s actually a little faster (when dumping and recreating the whole table, ymmv when inserting).

    I’m not 100% sure if it was MSSQL, though.
