WebTL;DR. The Policy Hash Table has 3-6x faster insertion/deletion and 4-10x increase for writes/reads. As far as I can tell, there are no downsides.

To do that it performs following steps, 1.) It will allocate a bigger chunk of memory on heap i.e. almost double the size of previously allocated. 2.) Then it copies all the elements from old memory location to new one.

WebMap is a key-value type data structure. Internally it is implemented as RB tree. Key is used to decide where to insert a new node inside RB tree. Value is just a data in the tree node.
