How to limit traffic for the whole server with IIS7?
There is a limit feature for a site, but it works only for a separate site:

Also there is Bitrate Throtting plugin for IIS, but as I know it can be configured only for a separate user:

Is there a way to configure traffic limits for the whole server, not for a single web-site?
UPDATE:
The solution is (thanks to @Arpit) setting <webLimits maxGlobalBandwidth="1000000" /> to machine config. But be careful! There is an error in IIS docs: you should type maxGlobalBand[w]idth (with lower case w), not maxGlobalBand[W]idth (with upper case W).
Well, I have not tried it yet but you can give it a go –
In IIS7, Select the server and open the Configuration Editor. On the right hand pane, there is an option to search the configuration. We are looking for
webLimitshere.This might be the key. More information about
webLimitscan be found hereEDIT –
I found this attribute for
webLimitswhich should help :maxGlobalBandwidth– Specifies the maximum total bandwidth for the server. Setting the value to 0 enables unlimited bandwidth for the server.The default value is 4294967295.
