HI!
I had the same problem as you have some time ago even if my problems
came from clients on adsl with a saturation limit on 0.8 Mb :)
I agree that this would be a nice feature but in the meantime I solved
the problem with trafficshaping on the storage daemon. I know it's not
funny to throw away perfectly good packages but it does at least only
give you one place of configuration instead of configuring all your clients.
I have a script that on workdaymornings shape the incoming traffic so
that it does not saturate the clients upload speed and after working
hours it removes the limit.
I'm using tc which is part of the iproute2 package.
My limitation can look like this:
tc filter add dev eth1 parent ffff: protocol ip prio 50 u32 match ip src
xx.xxx.xxx.xx/32 police rate 500kbit burst 3k drop flowid :1
I hope this can help you or someone else.
