ModRana also supports sqlite tile storage which CloudGPS will also support in a distant (like next year) future.
It was only a few months ago, in July, when the idea came up to use SQLite to power the graphics of Aciqra II. At the time, it seemed like a great idea. SQLite is fast, ate up little memory and is easy to implement. Even though this was confirmed by tests conducted before the process began, what was not clear was that it is not fast enough. SQL database systems are built to do many things but powering a graphics engine is not one of them. An investigation into the source of the slowness led to the discovery that each SQLite query takes up to 0.2 seconds to execute.
