I can download a single file at a time on one machine at 550kb/s. This is how jdownloader has worked for me for a couple years now on both machines. Now, immediately after installing the beta client, one machine is fine but the second machine no longer gets full speed *per file*. On the second machine, if I want the client to reach my full speed, I have to two files run concurrently.

The fact that I can get full speed if I download more than 1 file at a time on the second machine, and I always get full speed downloading 1 file at a time on the first machine leads me to conclude theres some limit that's been set.

As I said, the second client has changed a few settings willy nilly after updating. These odd occurrences only happen on the machine that no longer gets full speed 1 file at a time.
Where can I find the settings for limits and how can I change them to have no limits? It's not the hardware, isp, firewall, or servers.

Thanks in advance for your time.
