To download the blockchain with maximal speed you want to be connected to nodes with high bandwidth.
On default bitcoin will search and connect to random nodes. One can add nodes to bitcoin conf to tell bitcoin to connect to specific nodes.
To add a node to the bitcoin client to connect to, add the following to the bitcoin.conf file in:
Windows:/appdata/roaming/bitcoin/bitcoin.conf
Linux: $USER/.bitcoin/bitcoin.conf
ADD THIS TO BITCOIN.CONF
addnode=127.0.0.1
To find high bandwidth nodes go to:
blockchain.info/hub-nodes
for example and browse the hub nodes section. It is not required to add the node port, bitcoind will find the correct port.
.... Enjoy downloading at full speed.
EDIT: since the question / answer gained such an attention i decided to make this a community wiki :)

I think it is also important to note that the upcoming Bitcoin 0.10 release includes headers first download, and parallel full block download. That significantly decreases the sync time if you have a reasonable fast internet connection. It is currently at rc1 status, but seems reasonably stable, so if sync time is a serious concern you may want to check it out.
1 0.10 is now stable and already on 0.10.2 (https://bitcoin.org/bin/bitcoin-core-0.10.2/).

here is a free download website. you need a torrent client but they have a very stable and fast download because of multiple servers

I would always suggest to download from the SOURCE NETWORK with a predefined list of TRUSTED BITCOIN NODE SERVERS.
Please be also aware of targeted attacks by malicious websites. – Aurigae – 2015-10-18T03:59:54.160

I was confused that bitcoin.conf wasn't there, wondering if something had changed. But it turns out you can just create it (coming from: https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File).

When I go to
– User – 2016-01-12T13:06:45.520http://blockchain.info/hub-nodesthere are no nodes listed. The page has headers for information such as IP, Relay Count, etc but no actual data. In the sites footer there is a link tohttps://blockchain.info/connected-nodesis this the same thing?Does this answer apply anymore to bitcoin core version 0.11.2? Under Windows 10 there is no Bitcoin folder anywhere under AppData. – User – 2016-01-12T13:13:55.267
For fun & learning only ... another little hack - https://github.com/alphaaurigae/log-est-connections - with the script you can log ips on a specific port to a file. Theoretically one could use it to compile a list of add nodes / seed nodes . However, i feel this might be against some crypto basics not centralizing the connections. Use with care. Additionally, heres a sed script sample to modify the crypto source for more connections - however . your node will be marked "dirty" of course but makes thousands of connections.
