compatibility and bandwidth saving. Memory issues by caching should not arise, as the used cache will (in our previously used cases) only cache index fields and max. 200 relation rows. I tested performance on my machine: By fetching 400kb of data twice via mysql_fetch_row() -> mysql_data_seek() -> mysql_fetch_row() this was performed in 0.25 seconds. By fetching it once and caching in a PHP array via mysql_fetch_row -> foreach this is performed in 0.32 seconds. With usual data as used in PMA (10kb) I could only detect a performance change of 0.009 seconds, which is respectable I think. By not using mysql_data_seek we are later able to use global mysqli USE_RESULT options to fetch rows singly. I discussed that yesterday with Rabus, and if there are any objections we can surely discuss that further on the list.
