 ### Notes
 * We did a complete rewrite of the benchmark suite for this round. The results are note comparable to previous rounds.
 * The results should be now much more accurate and vary less.
-* Before each test the Garbage Collector is manually run to eliminate influence of garbage from previous tests.
 * The benchmark suite now includes concurrent test. These are probably the most interesting tests.
+* The memory footprint (per query) is now also measured.
+* Before each test the Garbage Collector is manually run to eliminate influence of garbage from previous tests.
 * The benchmarks are designed to minimize response latency from the server. We try to compare driver performance here and not to test the MySQL Server ;)
+* The memory footprint includes allocations by the database/sql package. In fact, for Go-MySQL-Driver 1.1 this is the large part, as you can see [in this memory profile](http://files.julienschmidt.com/public/go/sql-benchmark/mysql.PreparedQueryConcurrent4.mem.svg). The `mysql-rows.(*mysqlRows).Columns` block will hopefully elimnated after the Go 1.2 release [with this patch](https://codereview.appspot.com/17580043/).
