Chapter 6 Maintaining MetaFrame 139

Network

When monitoring network performance, examine the total bytes per second

passing to and from the server. Compare this with the speed of the network being

used to transfer the data; for example, 10Mbps or 100Mbps Ethernet, or 4Mbps or

16Mbps Token Ring. (Because these values are in bits per second, divide by 8 to

get the number of bytes per second; for example 10Mbps Ethernet is actually

1.25MBps.) If the server’s total network throughput is close to the network’s

transfer speed, the network is saturated. Possible solutions are listed below.

Upgrading the Network

Add a faster network backbone

Add a router between network segments

Connect the servers directly to the backbone

Upgrading the Server

Add a faster network adapter

Use the latest drivers for the network adapter

Assign a lower interrupt for the network adapter to give it higher system

priority

Monitoring Users and ICA Sessions

MetaFrame supports multiple simultaneous users logged on to the MetaFrame

server from a variety of connections. You can use the Event Viewer to examine

events such as user logon and logoff and connection activity. You can use

Performance Monitor to track resource consumption by user or connection, or

diagnose connection problems by examining statistics gathered on a per-user or

per-connection basis.

For example, you can monitor the amount of processor time being used to identify

potential performance problems. Statistics can be used to find and diagnose

connection problems, such as a defective modem or WAN link, by finding

connections with excessive error counts.

Virtual Memory

In a multiuser environment like MetaFrame, the demand for memory is higher

than in single-user environments. It is, therefore, recommended that the system’s

pagefile size be increased.

1. In Control Panel, double-click System.

The System Properties dialog box appears.

2. Select the Advanced tab.
