Do you want to go through the effort of making it faster? If no then seek a hosted database. If yes then you can load a mysql databases into memory and whamo you have super speed. Google "mysql.conf". Do you need faster writes more than reads? Mysql might not be what you need.
Thanks for perfect guidance. I want faster read than write. Will surely follow what you said. As my database size will not be more than a GB it will not be difficult to load into to memory and run it.
Best of luck!
