140 MetaFrame Solutions Guide

3. Click the Performance Options button, then the Change button in the

Virtual Memory section..

This opens the Virtual Memory dialog box.

4. Set the Initial Size and the Maximum Size to correspond to the calculated

value, which is 2.5 times the size of the system RAM. For example, if you have

256MB of RAM, set the Initial and Maximum sizes to 640MB.

Setting both the Initial Size and the Maximum Size to the same size

provides the best performance because the MetaFrame server does not take

extra time increasing the paging file.

Spreading the pagefile across all available drives improves the performance of

your MetaFrame server because the MetaFrame server can perform Read and

Write operations to more than one disk simultaneously.

Third-Party Technologies for Prioritizing ICA Traffic

Here are two solutions for ensuring that ICA packets are prioritized and routed

properly in busy network environments:

Cisco Queuing Technologies

Packeteer (PacketShaper)

Cisco Queuing Technologies in a Citrix Environment

For organizations using Cisco routers, a method exists for prioritizing the ICA

protocol when routing over low bandwidth links such as a serial connection. Cisco

offers two methodologies for prioritizing the ICA protocol. These methodologies,

Priority Queuing and Custom Queuing, relate to ICA traffic prioritization over

ports 1494 and 1604.

Routing is critical for large enterprise networks to function properly. Only

qualified personnel who are well versed with Cisco technologies should perform

router configuration.
