Hey,


I just got FrostWire and made some downloads with it. It appears, that e.g. when I try to download an episode of "....", I get an DL speed not higher than 49 kB/s having DSL
for 600 kB/s. But other times, I get an speed of 300 or 400 kB/s.
I think having noticed, that everytime I try to download a file with a bigger size, like 350 MB the speed is that low.
So, can you help me?

BTW: I have FrostWire 4.10.5, the current version, I guess.

Depends upon the upload speed of those sharing the files. Remember you can only download from 8 sources at once.

When you are getting up around 3-400 you must be be pulling down of mainly really high speed connections, capable of 50 each

it can also be down your firewall blocking some incomming connections..this happened to me when i first installed it a while back

FrostWire says a firewall is acivated, although I quit my Sygate Firewall and deactivated the Windows Firewall too.

then you have to configure your windows firewall if switched on (this is presuming you have windows firewall switched on)

also, if you have a router, open the ports on there.

Which port numbers?

typically for P2P its 6881 to 6889

6346 is the default Gnutella port. If frostwire cannot open that port or if the port is in-use then it will change. You should manually port forward the router and setup the forwarding option within frostwire.

Just curious, what's the reason for the 8-source limit? I've been wondering about that, and trying to figure out how to change it, ever since I started using FrostWire (which is a great program, by the way, the developers rock).

Thanks!

The limit is there to avoid causing overhead for transfers (ie lost of upload speed for communicating to many hosts)

Take it like that 100 hosts swarms between themselves. They get 8 dl sources and 8 uploads slots taken, they share as much as they give. Now, everybody gets the same speed, ie 80KB/s.

Now take case 1: everybody downloads from everybody, 100 sources, 100 uploads slots, here just to maintain active connexions for transfers up and down transfers (http consume badnwidth to maintain transfers), you would loose like 5-10KB/s of real transfer speed both in DL and upload, making transfers SLOWER than my first exemple. Not to mention that without caching of transfers in RAM (higher ressources consummed both CPU and RAM), you hard disk you scream like crazy and lower its life.

Anyway, its a multifactorial answer and there are many other factors, but there is an efficiency limit to increase # of hosts you dl from. This limit is higher as pipes and computer get better (previously FW was limiting at 6 sources), but this will increase as technology improves.

Hope you understood

Ciao
