if it is working or not, I guess it will take a while until checksum caches

I'm seeing terrible backup performance on my backup servers, the speed
has slowly degraded over time. Although, I have never seen speeds higher
than 1MB/s. (We have it set to do no more than 2 backups at a time.)
Here is our setup:
Our network is all 100Mb between servers, and switches, and
