What causes bittorrent to consume so much memory, even using utorrent?

[DoubleIPA]

Just curious if there is a more technically minded poster here who can give an explanation of why bittorrent clients, even the tightly coded utorrent, can eventually consume over 500MB of memory footprint after a certain point. I do have typically >10 active torrents and am trying to free up resources. Do active connections per torrent play a factor?

Thanks.

Making a run for it?

I have 40 open torrents, 18 of which are active, with about 400 active peers and about 2000 inactive peers. I'm DLing and ULing at 90% of my max (2.3 mB and 500 kB respectively). I recycle my router once a day, and occasionally I'll turn my computer off and back on again, but, for the most part it stays on for about a week at a time. I think the last time I turned it off was 4 days ago. In other words, it's been on and in that 40 torrent realm for about 4 days.

My client (utorrent 1.6.1) is fluctuating between 30 and 40 mB of memory usage. Firefox, on the other hand, is sucking up a whopping 100 mB of memory. I do have the 20 or so trackers that I use on a daily basis open in separate tabs, though.

I have the same usage for utorrent (1.7 here), around 20-30mb according to the task manager. In fact, just going by the task manager there is no real resource hog to speak of. However after letting utorrent fly for a day or two, my initial memory usage (total) goes from around 300MB after logging in and launcing utorrent to over 700MB! I know this is something to do with BT because as a test my rig never goes over 350MB for days on end if I do not start torrenting.

It would just be nice to know what exactly is taking up that much resources, because it escapes the gauge of window's xp task manager.

Not sure about your problem, but a better alternative to Task Manager is Process Explorer, available here: http://www.microsoft.com/technet/sys...sexplorer.mspx

Thanks for the link. I used to follow sysinternal's work years ago. It looks like Microsoft doesn't meddle in their affairs much as this is still a great tool. I think the culprit is that I have hundreds of connections to TCP, or open files to Device\TCP according to Process Explorer. I guess that would be the source of the overhead, and not much you can do about that if you want to have hundreds of connections per torrent?

Yea, my Utorrent is only using 11mb. Now Azureus that was a different story. That things used a ton.

My Utorrent only uses around 10mb
