Subject Re: ACS 4.4.1 network.throttling.rate - Advance Zone- XenServer 6.2
Date Thu, 18 Dec 2014 20:16:11 GMT
hi ilya,

I configured "Global Setting"  set "0" to network.throttling.rate, 
rebuild the VR reboot the machines but network rate still under 20MB. I 
did restarted the management server as well.

I don't know what else to try!
