can i make bitcoin-qt to make more than 8 connection?

can i make it to make 20 connection's

because download of the block chain is very slow

but downloading the block chain isn't what makes it slow, it is the verification which is hindered by your CPU and IO js adding more nodes wouldn't make a difference.

Number of connections goes up with time. Initially it's just 8, but after few hours you should be have much more connections.

it has been 6 hours till now and only 8 connection

is there a way to get more connection's

As was stated - this won't increase the speed of your blockchain download at all.

If you want to download it faster then better to download it as a file (that can be done from various sites) - although I guess it's now two files not one.

You might be firewalled. 8 is all I have ever been able to get without tweaking. I find 8 to be enough.

I have the impression that, if your node is not listening to incoming connections, bitcoind will not attempt to establish more than 8.
Can some one confirm that?

OP, if you want to listen to income connections, maybe you should check if port 8333 is open in your firewall. In case you have a router/NAT, redirect its 8333 to your computer's 8333.
If you don't know what the hell I'm talking about, just ignore this and be happy with 8 connections, it's enough, and it's not the reason for the slow blockchain download as others have pointed. It's IO more than anything.

Correct. The Bitcoin.org client will made eight outgoing connections.  So either the client isn't configured for UPnP or the network doesn't support it or the network (or local system's software firewall) is restricting port 8333 traffic from reaching the client.

if you want to download it faster, you just use the -connect option and connect with a fast peer, someone hosted at ovh or hetzner or something.

i had mine set to deliver 5000 blocks at once, because of the bug where ppl request blocks over and over and over.  with 5000 at once, it'll cause most of the clients to ban you for 'flooding'.  there were a few ppl that got up to 130000 pretty fast, though

You can establish more connections by increasing maxconnections (above default of 125):

That will let you serve a larger number of requests, and thus spew more blocks than a smaller limit might.
