optimize LAN seeding on 1Gbit/s nerwork

[sade]

Hi,

I'm currently using utorrent in order to deploy a lot of data (chunk of 10GB) over a small gigabit network. .

The first tests I did tonight with the last official release are not really fast (not as faster as I could expect In fact

From one computer to another , I get about 35-40 MB/S the first seconds, the 2MB for 30s , again 35 , and then periodic.

I capped the upload bandwith of the seeder to 35MB/s and now , I do no have anymore the 'wave' effect.

But now I get 35MB/s the first twenty seconds, and after I got a regular 14MB/S.

I guess I could obtain a faster regular speed , but how can I optimize the parameters for such a Gbit network ?

Thanks in advance !

Try turning off bt.tcp_rate_control in Advanced. This won't help much in LAN situations and will very likely break things.

I just tried that without any results

I think it's more related to the reading/writing cache system than the network. Indeed , the first seconds , when the cache is filled , the network speed is very high and then ,then when the cache is full, it slow downs ... I could observe that with the graph.

But I don't know how to optimize the HDD part :-/

We actually have some ideas on how to improve disk i/o and they will be in the next version. The only real fix is well, faster HDDs. YOu could try disabling the cache and letting Windows handle it. In some rare cases this will give better performance.

The HDD can sustain min 100MB/S ... I don't think a little 30MB/s can disturb it ;-)

Maybe in real situation , this week end , with 2 initial seeders and 6 peers , it will go faster

(the goal being to fully use the 1Gb bandwith)
