Performance
This section lists considerations related to performance.
View Data
If you are monitoring your CPU through the task manager while using View Data,
you may see spikes in resource usage due to sorting. To reduce the load on the
FactoryTalk Historian ME processor, sorting occurs on the client computer.
Web Interface
This section contains web interface considerations.

The System Status will refresh every 30 seconds to show the current status of
several key module services.

The FactoryTalk Historian ME web interface supports two primary methods for
IP address configuration, DHCP (the default) and Static. If you change the
module’s default IP address configuration from DHCP to Static, or if you use
BOOTP through an RSLogix and a BOOTP/DHCP server, you cannot access the
module using its host name. The new IP address is not associated with the module
host name on the DNS server and the host name does not resolve. To work around
this issue, we suggest you work with your local IT department to register the new
IP address with the DNS server.
See the “System Status” section for a description of the status information.
