Download OK but Upload speed very slow

Question

Slow Upload Problem
Caused by Windows 8 One Drive Program being active. Eats up all upload capability.
Cntrl, Alt, Delete: Process Tab, scroll to One Drive, right click, end task
To check problem: Performance Tab, scroll to bottom, Ethernet, S:0 = fixed, S:400 = problem
To disable One Drive:

Hi Julio,
We have removed the class-map for IPS and have done a clear local-host.
We have also changed the duplex (from Auto to full) and speed (from Auto to 100Mbps) on the outside interface.
it seemed the duplex we 've got was half when it was configured as Auto. We've asked our ISP to change in their side to full, but we've got half instead.
We did an upload test after those actions, the speed we got is 300KBps, it should be 8Mbps (download and upload).
when we send many upload at a same time, we can see from our monitoring tool that the bandwidth used is 8Mb.
We wonder we cannot get high speed when uploading a single file, the max speed is 300KBps.
Please, find below the output of
sh int | inc error
        0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
        0 output errors, 0 collisions, 1 interface resets
        0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
        0 output errors, 0 collisions, 1 interface resets
        0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
        0 output errors, 0 collisions, 1 interface resets
        0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
        0 output errors, 2710 collisions, 3 interface resets
        0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
        0 output errors, 0 collisions, 0 interface resets
the 2710 collisions is on the outside interface (i think it was before changing duplex)
sh cpu
CPU utilization for 5 seconds = 2%; 1 minute: 1%; 5 minutes: 1%
when we plug a computer directly to the ISP device (IDU), the speed is high (about 650KBps).
what would you suggest us to do? (sure, we will rate all the helpful posts )
