Laptop runs slow with high dowload speed in utorrent

[sachingururani]

Hi

I m using my mum's acer aspire 4736 laptop, with configuration as below -

Intel core 2 duo t6570 @ 2.10 Ghz, 1.19 GHz, 956 MB ram, 360 GB harddisk with Windows XP Professional version 2002 service pack 2

I am using a 1 MB broadband connection supplied By MTNL (combo 512) which normaly gives me a download speed of 100-120 kbps on utorrent. However, my speed can go upto 360 kbps in the morning or at night. The problem is, i've noticed that as soon as the speed goes anywhere upwards then 200 kbps, my laptop becomes very slow. Windows take time for minimizing, windows sounds are very slow and any kind of general multimedia content plays very slowly. Can anyone please tell me why is this happening...and if there is any cure...

Also, i have seen this same thing happen once when i had restricted utorrent speed to 15 kbps and my mum was talking to someone on skype...

The odd thing is, i have another laptop at home which is my own, its a Dell Inspiron 1736 with windows 7 and 4 GB ram, and utorrent never gets more then 150 kbps on this laptop with the same Internet connection. It never slows down either.

I have already got the acer laptop checked at the acer service centre. Those guys gave the cooling fan a cleaning and returned the laptop a couple of days ago but i still got the prob. Should i go to them again or is this problem due to only 1 GB ram?

Here's the data from my task manager, if it helps..i noted this when three I.E tabs were open with utorrent, and two folder open...my antivirus was disabled , and still the laptop was running slow, with utorrent speed of 356 kbps download, upload limited to 25 kbps-

I am no tech wizard, but these look pretty ok to me...so do u see any problems???

You could try updating your network card drivers (or wireless depending on what you're using)

More than likely its just a lag because its trying to deal with the increase in traffic, What kind of firewall are you using?

I think i have updated wireless drivers...and i was using kaspersky antivirus with its own firewall till a couple of days ago when i disabled it...my windows firewall is always disabled...
