I have done a test with DerbyPM. The results : creating 999 nodes on a node already containing 0 childs take 5402 ms creating 1 node on a node already containing 999 childs take 126 ms creating 999 nodes on a node already containing 1000 childs take 4292 ms creating 1 node on a node already containing 1999 childs take 137 ms creating 999 nodes on a node already containing 2000 childs take 3796 ms creating 1 node on a node already containing 2999 childs take 254 ms creating 999 nodes on a node already containing 3000 childs take 4702 ms creating 1 node on a node already containing 3999 childs take 370 ms . . . creating 999 nodes on a node already containing 20000 childs take 32841 ms creating 1 node on a node already containing 20999 childs take 9473 ms . . . creating 999 nodes on a node already containing 28000 childs take 41058 ms creating 1 node on a node already containing 28999 childs take 19228 ms as you can see. More a node have childs, more time is taken for create one child.
