No, I've tried that approach with a comparator like this:
static int
rnode_comparator(const void * p1, const void * p2)
{
return memcmp(p1, p2, sizeof(RelFileNode));
}
but it turned out to be slower than the current comparator. I've posted
some benchmark results and possible explanation on 20/12 (message
[email protected]).
If you could verify my results, that'd be great.
