mysql vs sqlite vs hsql

[Pierre-Frédéric Caillaud]

Level 1:

	- have you optimized your database design ?

	- have you cleaned your tables ?

	OPTIMIZE TABLE blah;


Level 2:
	- Send several inserts per query (you save on IPC time)
	- Use block inserts (inserts many rows at a time) => much much faster

	Read the mysql dox

Subsidiary:

	What's this doing on the python mailing list ?
