final tweaking help... greatly appreciated

[spiked]

so i wanna get some final tweaking done to kinda perfect utorrent on my pc...

anyways ill go over some system specs really fast, i hope i give out everything needed so it is easier for you nice people

-----

Router : D-Link DGL-4300 (Gamefuel On + Game Rule Set + Static IP Set + Port Forwarding Done)

Firewall : Sygate Personal Firewall Pro (Port Forwarding Done, Program Full Access)

NIC : 10/100/1000 Gigabit NIC Card (Linked with Gigabit Speeds to router)

PC : 2GB Memory, Opteron 165 Dual Core, 7800GT, 1TB + HDD Space, All update drivers and software

Internet : Comcast 8mb Down / 768 Up (10mb+ down on dsl reports and average 720 on up speed testing)

Current WinXP Tweaks : Static IP Set, EvID Patched to 75

-----

current problems : Only 1, and it seems to be UPnP. My router supports it and i use it, but i still get the error on the upnp mapping

using uTorrent 1.5

"Unable to UPnP Port to 192.168.?.???:53000"

-----

a quick picture of what i can get at my current settings (*NOTE* i let this torrent run for at least 5 minutes before taking snapshot)

i averaged 706kbs on this torrent and it took 30minutes at 1.18GB by the time i got done writing this post it was done downloading lol i also maxed out my down limit which was set for 978kbs for almost 8 minutes

anyways here's my settings for uTorrent

*General* : All options checked except for start on startup

*Network* : Port 5300, UPNP Checked, Windows Firewall Option Unchecked (dont use it) and randomize port unchecked. Bandwith settings are 60/71/978 in that order and Disabled + Allow Legacy checked on the Protocal options.

*Torrents* : In order i have 598 - 74 - 15 - 4 - 4 with all options on the bottom checked

*Advanced* : everything is on default except the following

net.max_halfopen *60

bt.prio_first_last_peice *true

peer.lazy_bitfield *true

peer.disconnnect_inactive_interval *600

diskio.write_queue_size *16384 (16mb)

diskio.read_cache_size *524288 (err cant remember this one exactly)

-----

so i would be appreciated on some last helping tips, and any suggestions

i hope since this is my first post it wont be my last post, i learned alot of things from reading these forums. And i use alot of this info found on these forums to help out people that are new to utorrent.

If i have broken any rules mods please lemme know

Since you forwarded your ports manually, disabled UPnP in µTorrent (Preferences > Network). It'll get rid of that benign error message. And that's it -- assuming you ran the Speed Guide, everthing seems about right =]

Ultima: yup thats where i started

[proto09]

why dun u try to patch ur xp to 300 and set net max half tcp to 270. maybe u can also try to enable protocol encryption. under torrents can try to set max no of connected peers to 270. see if this might help u further.

[Ultima]

Because there is absolutely no reason for that many half-open connections to be made. Like I said, his settings are perfectly fine already, and he seems to be getting great speeds, so no further alterations are really needed.

because my router cant handle them and will easily shut down

I think you're mixed up about kbs and KBs, you meant to write KBs

I guess you need some good connection and torrent for that

anyway, I just configured this Dlink 4300 router with gamefuel and it works real nice with p2p so far, I can even play online games and download/upload at the rate which would otherwise cause two step lag in MMORPG I play

when I got this router few days ago, I thought it was clear RMA case (would disconnect from my PPoE DSL every 2.5 mins and reconnect half a min later and it did this with quite precise timing - nothing to do with p2p) but then I flashed firmware to latest and it is a winner

one thing about settings, I had max # of connections set to 100 which might have been uTorrent installation default and with this Dlink I was getting poor downloads, about same as my uploads @40KB and it improved lots when I set those connections to 200 and so I set it to 300 and it improved still, so I went and kicked in 600 and now it seems it leveled off improving after some additional rise, so I will leave it at that and its running good like this for couple days now, no probs

now my other settings might be off relative to allowing so many connections but I suppose I should ask about that on other thread

So you're allowing up to 4 torrents at once (be they seeding or downloading) with at least 15 upload slots each at once. 4 torrents times 15 upload slots each is 60 upload slots. You set upload speeds to 60 KB/sec (71 KB/sec while only seeding), so that means each upload slot can expect about 1 KB/sec on average. If you're only sending 1 KB/sec to someone, the way BitTorrent works they may give you little in return because others are giving them alot more. Your BitTorrent client (µTorrent) will seek connections that DO return the favor, and with as much as possible, but you may be shortchanging yourself in the process. Try reducing upload slots to only 6 per torrent. Even if you're only running 1 torrent, that's still only 10-12 KB/sec upload speed per upload slot -- but that's plenty enough for the more generous uploaders to return the favor equally, plus seeds will also give you a bit as well. If you have 4 torrents going, that's 24 upload slots -- so average upload slot speed would still be 2.5-2.8 KB/sec. That doesn't sound great, but it's more than most people give.

You've also got global max connections set to 598 and connections per torrent set to 74. (Odd numbers there, but to each his own.) With only 4 torrents allowed at once, each having 74 connections...that's 296 connections for the 4 torrents max. DHT isn't counted as connections, it's just "connectionless" UDP traffic. It's possible you could end up with LOTS of very slow torrents that don't count against the max active torrent limit, but I doubt they'd need 302 connections. You could lower max global connections to 300-350 and probably change nothing. So there's no harm with your values...I just don't know what you're thinking.

D-Link routers even with the latest firmware probably will have problems once they top out over 200 connections at once, especially if there's lots of connections being closed while new ones are being made. I've personally got an old Linksys router that needs to be reset every few days to a week for it to work at its fullest. It needs to be reset more often if I stress it with 200+ connections at once.

Think about the other side of the equation in your quest to get the fastest download speeds possible! :mad:

Quick question: What do you think 40 KB/sec upload looks like when it's split 600 ways?

That's ok, you probably don't have that many upload slots...so hopefully they don't have to see an average download speed from you of 0.067 KB/sec.

There will just be potentially 500+ connections that never get anything back from you.

If you seed long enough, they'll either eventually get something from you...or they'll finish the download with someone else's help. If I were betting, I'd put alot more money on the latter than the former.

This is why it's a good thing ludde isn't allowing people to click-ban ips in torrents, many people might be doing that to yours.

Switeck: Ive recently changed it back to 2/2 on running torrents it was just 4/4 for peformance adjustments. And i seed till a 3:1 ratio on all torrents i download on private trackers, or if on a public tracker i seed till 100+ seeders are available (mainly because on public trackers they are just leechers anyways, and i get 99% of my files from private trackers). But right now im switching to 4 upload slots per torrent at 2 uploading torrents at 65kb/sec should give me 15kb/sec per leecher, but i see what your tryin to say and thx

i just brought over a few settings from azureus and they seemed to work just fine so i decided not to bother tweaking them anymore, but i adjusted it to 400 max connections at 100 connections per torrent with 2 torrents going at once, which leaves me a few download slots if i want to start an extra torrent and throw it on FORCE START.. so it now looks like 400-100-2-2-2

ive never had a reset since tweaking to my current settings at all.. and with the new 1.7 firmware on a quick release i doubt i ever will

vanDivX: yeah 600 is way tooo high... but hey wat do i know

Almost.

2 torrents x 4 upload slots each = 8 total upload slots.

65 KB/sec divided by 8 upload slots = 8.1 KB/sec

or 16.25 KB/sec if only 1 torrent is running.

Either way, they'd see you as a big uploader and devote more of their own upload back to you.

...if they're not running a cheating client that is.

[spiked]

whoops... i think you missed the part where i switched to 2 max upload/download

[Switeck]

Btw, don't quote so much -- especially from a post immediately above yours.

I reset my cablemodem and router not because they've crashed but because of the gradual reduction in performance after running µTorrent (and other file-sharing programs) for days straight. Maybe it's some minor buffer overflow or "just getting further back to the paint bucket" (router or modem having to check every previously stored connection value to make a new connection?) that causes the slowdowns. I don't know why. It's more or less a precautionary thing. I once let µTorrent upload for about 1 1/2 weeks straight without reboot, so it's not a required thing...just if I want that last 5% of performance I do it.

Your sentance which I quoted said 4 upload slots, 2 torrents, 65 KB/sec upload speed, and 15kb/sec per leecher. I was commenting about those settings, which I didn't say was "bad" only that the math worked out a little differently than 15 KB/sec per upload slot/leecher.

I did notice you changed later to 2 upload slots. Ironically, using only 4 total upload slots (2 torrents x 2 upload slots each) with 60+ KB/sec upload speed might result in slower download speeds than using slightly more.
