yeah i know it's not supposed to be constant. but my graphs are coming up with too distinct patterns to be normal.

what could be the problem?

RAM or Hard Disk problems, more info is required.

Is your hard disk up to scratch with handling high speed downloads?

well yeah my hdds are only about 3 months old max. i'm using 3x 500gb (2WD 1seagate)
what info do you need?
i'm using 2x 1gb crucial ballistix ram.

^^ That kind of info, which should rule out RAM & HD probs, but not entirely if one is found to be faulty.

What is your line speeds?

Do you have max settings for up & down set? (which should be about 80% of each - not max, then increase in 1% increments and find out which setting suits you best)

Have you set up utorrent in accordance with any guides pertinent to your line speeds? Or is it just default from the box?

i've been using utorrent for over a year. it's only recently that this problem has arisen, but i can't pinpoint to one of the changes i've made. like version update/ microsoft update/ additional HDD/ Cfosspeed etc

i'm jus tlookign to see if someone else has the same problems as i do, to troubleshoot from there. i've capped my upstream to about 30 although my isp provides about 45. when i'm using up more downstream though upstream drops automatically to about 15-20 or so and doesn't even reach my cap of 30 that i put in place.

line speed's 10mbps/384kbps

I would run some serious hard disk tools to check for errors & redundancy & fragmentation to rule out HDs, from the info you have supplied it looks like data is corrupting on write out to your hard disks.

Then move your utorrent data downloads to the best drive you have, and then report back.

Search for Hirens's boot CD V9.4 for the best data tools there is.

Have a look at "Disk Statistics" in utorrent and see if you spot anything odd there.

okay i've download hiren 9.4 like you said. what am i supposed to use in here now? sorry i'm just not familiar with it =)
i have about 1TB of torrent data and it spans across all 3 hdd. even if i consolidated, it'd still be more than one disc. okay and i'm not sure if this matters. but when i try to defragment the drive that only has torrent downloads using the windows defragmenter, almost the whole bar is red, even after defragmenting. does that say anythign?

Before I let you loose on HD tools, you had better do the MS safe hard disk check first:

Does this happen only with utorrent? Have you tried using another bt client? And do you get memory errors or BSODs frequently?

If you are using XP, check for 'savedump' entries in Control panel->Administrative tools->Event Viewer

There are a wide range of possibilities for this including ISP throttling.

i don't think it's isp throttling because my speeds aren't limited for stretches in hours, but the drops and jumps in speed occur multiple times in a short span of time, which suggests that it is a localised issue. Seeing as this is not a known problem with utorrent, changing clients might not bring the desired outcome, and in fact my complicated matters further.

yes i have had some bsod problems recently, but they only occur if i run both emule and utorrent at the same time. if utorrent is the only p2p programme running then i don't get bsod. the error is: bad_pool_caller, which, according to some preliminary searches on google, is caused by bad drivers or usb connections.

i am able to access event view but i don't see this save dump you're talking about. i've checked in the minidump, and have used the windows debugger to determine some of the files that might have caused the errors, mainly vsdatant.sys(associated with zonealarm) and ntoskrnl.exe(critical windows boot component). i was about to do a repair install on windows xp, but oddly enough, this problem has suddenly ceased. i'm getting relatively constant speeds with utorrent now.

might be firewall prob or isp prob checkout
