JDBC has a feature called batched statements. To put it simply, an SQL statement is prepared, sets of parameters are added to the batch, and then the batch is executed.

Currently, Jaybird takes the list of parameter sets, and executes each one with isc_dsql_exec2. Other databases have APIs that allow the entire list of parameter sets to be sent across, and the server then loops through them, executing each one in turn against the prepared SQL statement.

This greatly reduces wire traffic, with equally large gains in performance.
