remember when I compared using bulk copy to insert 104,000 records into another database? I compared it to dataadapter update using batch updating with the size set at 100.
The difference in November CTP (VS2005 and SQL Server 2005 full version) was 21 seconds for the bulk copy and 41 minutes for the update.
Out of curiousity, I just ran this again with the Feb CTP versions of vs2005 and sql server 2005.
The bulk copy was about the same. But the update using the same table and the same settings took only 8 minutes!
update: Pablo Castro recommends: “For maximum perf in batching, make sure you wrap the batched update around a transaction.“
