Number of connections affecting dl speed??

[psycho2048]

my system config is:

-uTorrent status: "Network OK"

-DSL, about 140 KB/s down; 40 KB/s up;

-Windows XP (SP2+latest updates), WRT54G router (v2.2) with Firmware Version: HyperWRT 2.1b1;

-Software Firewall: McAfee Personal Firewall;

-NOT FIREWALLED (port-forwarding is correctly setup)

-malicious traffic shaping??? i dunno, i use SBC Yahoo! DSL

what would be the optimal up/down settings for uTorrent? i mean max connections, connections per torrent, upload slots? right now uTorrent is using the default settings and my download speeds went down from about 110 KB/s (on my previous BT client) to about 60 KB/s (on average, it wavers from 30KB/s to 70KB/s);

thanx in advance

2.1b1 tofu11 I hope?

And uh, did you cap your upload speed? If you upload at about 40 KB/s in reality, you should use ~32 as your upload cap.

At those speeds, the defaults are probably best. Could try raising upload slots to 4 and connections/torrent to 60 though.

hmm, not sure about the tofu11 thing. how would i check that?

also, right now i'm connected to about 140 seeders and 120 peers, with the average dl speed of 80 KB/s... wouldnt my speed drop if i limit it to 60 connections?

oh, and my upload speed is capped at 32 KB/s (with 4 upload slots). lol i forgot to mention that

Whoa, you're using that many connections?!

Damn man, I've got 5000/470 and I use 75 only.

That many connections is likely to slow things down with your upload speed. Too many connections = even more BT/TCP overhead (both download and upload) = slower speeds. More connections != better/faster

The router page should say the firmware at the top right.

Mine says: Firmware Version : v4.20.9 - HyperWRT 2.1b1+tofu9 (cause I haven't upgraded)

Also, read this.

so many connections IS NOT GOOD? ok then, how many would you recommend for my connection?

i've read the thing on startup router scripts (and yes, i have the startup script enabled), but i've just realised i have the HyperWRT, but not tofu11 version thanx for pointing that out

[Firon]

Like I said, 60/torrent, and maybe 200 global.

Also, for your startup script, I hope you're not using any of the gc_thresh things, those make performance -worse-.

[psycho2048]

i'm using the startup script listed in the faq:

echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts

echo 1 > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses

echo "600 1800 120 60 120 120 10 60 30 120" > /proc/sys/net/ipv4/ip_conntrack_tcp_timeouts

[Firon]

Oh, ok.
