Optimization in KDE Base
Optimize WinCE db performance by removing indices.
SQLite benchmarks on Windows CE have shown that creation
and maintenance of indices are expensive. It has to be
evaluated if they are used by SQLites query planner
with the statements by Akonadi anyhow. Tests have shown an
improvement for initial sync on WinCE of ~40% which is
also the difference we saw benchmarking many insert statements.
