C＃将数据插入SQL数据库的最快方法

I am receiving (streamed) data from an external source (over Lightstreamer) into my C# application. My C# application receives data from the listener. The data from the listener are stored in a queue (ConcurrentQueue). The queue is getting cleaned every 0.5 seconds with TryDequeue into a DataTable. The DataTable will then be copy into a SQL database using SqlBulkCopy. The SQL database processes the newly data arrived from the staging table into the final table. I currently receive around 300'000 rows per day (can increae within the next weeks strongly) and my goal is to stay under 1 second from the time I receive the data until they are available in the final SQL table. Currently the maximum rows per seconds I have to process is around 50 rows.I am receiving (streamed) data from an external
