Performance Settings
Performance settings of the Web site hosted within the subscription are
defined by the performance node. This node is specified by complex
type DomainPerformanceType (plesk_domain.xsd) . This type is
structured as follows:

- The bandwidth node is optional. It restricts the network use by the specified value (Kb/sec) for the subscription. Data type: integer. If set to -1, the bandwidth is unlimited.
 - The max_connections node is optional. It restricts the number of connections by the specified value for the subscription. Data type: integer. If set to -1, the number of connections is unlimited.
 
The following sample packet creates a subscription and sets performance settings:
<packet>
    <webspace>
        <add>
            <gen_setup>
                <name>newsite.com</name>
                <owner-id>1234</owner-id>
                <ip_address>192.0.2.123</ip_address>
            </gen_setup>
            <performance>
                <bandwidth>1000</bandwidth>
                <max_connections>20</max_connections>
            </performance>
        </add>
    </webspace>
</packet>
To undo the performance settings for this subscription, send a packet as follows:
<packet>
    <webspace>
        <set>
            <filter>
                <name>example.com</name>
            </filter>
            <values>
                <performance>
                    <bandwidth>-1</bandwidth>
                    <max_connections>-1</max_connections>
                </performance>
            </values>
        </set>
    </webspace>
</packet>
