New computer build, new uTorrent version, my 2007 computer/uTorrent way better

[boneychil]

Ok...So here's my story. I'll keep it as short as possible

 

i recently did a new computer build.:

 

Old computer was compaq presario, all 2007 stock except for RAM and nVidia 8800 video card (for back when I was gaming) with Windows Vista (YUCK). I had a pretty old version of uTorrent but it worked great.

 

Always could set priorities and always would be throttled to 900kb/s and could download as many torrents i wanted at once without any problems.(I dont know exactly what version I had, definately before version 2.2.1.)  Now with the new computer that works great, no problems, I have downloaded the newest version of uTorrent 5 days ago (6/20/2014) and noticed that when I have more than one torrent going, something throttles me down to under est. 20kb/s.

I tried downloading an older version 2.2.1, it works better, (only a third as fast as it should be)  but really would like to know if there is some settings i could adjust so I could download multiple torrents without the loss in speed.

I tried connecting my old hard drive up to find out what version I had, but it needs to be re-partitioned into a new file format, from what someone said at Tom's hardware forum, and I dont know how to do that. Otherwise I would just use my old harddrive and Vista that is installed on it.

 

I need to know what version works best with windows 8.1. When I use the newest version, internet speed comes to a grinding halt. At least with the 2.2.1 version,  I am able to use internet still with only a slight downturn in speed.

Also, when I use the newest version and download one file at a time, I get my full bandwidth speed. When I start going multiple, my download speed goes way down, under 20kb/s and bandwidth alloction seems to not work. On my old computer that had the old version, I could prioritize, so most of the bandwidth would go to the file of my choosing.

 

 

Now I built a new computer and put it in the presario case:

 

ASrock motherboard

CPU

PSU

2x1GB RAM

HDD

optical disk

with windows 8/1

 

I've done speed test and get my alloted 1MB/s download rate from comcast

 

Questions:

What version works best with Window 8.1?

Why does the prioritizing not work in the newest build?

Why does it throttle me almost to zero when downloading multiple files?

 

Thanks
