Is this your address? Is the address in your wallet?
If it is not, then that command will not work. Bitcoin Core does not track all addresses, the overhead is too much and that is not what Bitcoin Core is meant to do.
oh ,get it , it is not my address
but I imported it to my Bitcoin Core , when I imported it， I choosed no rescan first time
Without rescanning it won't know about any transactions related to that address. You will have to rescan in order to get any information about it.
and now reimport with default(rescan)

it is very slow,
Yes, that is because it must go through the entire blockchain and scan every single transaction to see which transactions create outputs to the address and spend from those outputs, if any.
my further question is , why the blockchain.info has faster way to get the trans of a special address?
it shouldn't be that he has good server ,at same time he has lots users , while I am only user of my computer
Because blockchain.info is not just relying on a bitcoind. Rather they have at least one set up as a node, but they also have other software and an external database. This allows them to receive the transactions and write them to their large external database so that they can retrieve the information quickly. Bitcoind is not designed to do that because it is completely unnecessary. It is not supposed as a block explorer.
