[TYPO3-core] RFC: #8515: Speed up tslib_cObj->getTreeList by caching its results

[Steffen Kamper]

Hi,

here's my +1 by reading and testing.

As my local setup doesn't have huge pagetree my tests/measering may be 
not as significant, i had performance optimized by 1%-10% depending on 
the actions.
Most speed was with indexed_search with ~50 indexed pages.
I did some page copies / moves and all was ok.

one little thing i would prefer:

foreach($rootlineIds·as·$rootlineId)·{
	//·delete·the·rootline,·must·contain
	$GLOBALS['TYPO3_DB']->exec_DELETEquery(
	 'cache_treelist',
	 'pid·=·'·.·$rootlineId
	);
}

why not imploding the IDs and make one delete call?
