[Mono-list] Batch inserts with ADO.NET

[Cory Nelson]

I'm not sure how DB2 works but I had the same issue with MySQL.  I
created a simple class that creates insert commands like "insert into
<table> values(value1),(value2),(value3)" and flushed the buffer every
200 or so commands.  It gave an average 10x speed up.
