Can I force files to queue up?

Hi,

On one of my clients that have a huge amount of small files, can I force files to enter the queue?

In the beginning I was getting 150Mbit/Sec when files were being queued up.

But now, 0 files are in the Queue and the transfer speed is 5Mbit/sec.

Is there any way to speed up?

Yes, I am also.
The server version is UrBackup 2.0.33 installed in windows.
When I use the full file backkup, the file in queue is 0 and the speed is around 10 MBit/s.
