z_listreceivedaddress with no filters is very slow #353

z_listreceivedaddress RPC is really meant to be used with various optional "filter" arguments that don't exist in z_listreceivedbyaddress . But if no filters are used and it's called in the simplest way hush-cli z_listreceivedaddress zaddr then it's drastically slower than hush-cli z_listreceivedbyaddress zaddr . This should probably be in the RPC help, something like "Note that this RPC is much slower than z_listreceivedbyaddress if no filters are used. You should use that RPC if you don't need any filters."

For example, on one particular large wallet, z_listreceivedbyaddress takes 4.6s to return data while z_listreceivedaddress takes 1 minute and 53s to return data.
