Besides the system processor and memory, the hard disk is an important factor in system throughput. SCSI disk drives and adapters, especially Fast SCSI and SCSI- 2 compatible devices, have significantly better throughput than ST-506, IDE, or ESDI disk drives and adapters.

For the highest disk performance, you may want to consider using a SCSI RAID controller. RAID (Redundant Array of Independent Disks) controllers automatically place data on multiple disk drives and can increase disk performance and improve data reliability. More information about RAID can be found in the MetaFrame Solutions Guide.

The ICA protocol is highly compressed and causes negligible loading on a network, but because the MetaFrame server handles all network requests, a high- performance network interface card (NIC) is recommended.

If a multiport asynchronous communications adapter is installed for supporting serial ICA connections, be sure to use an intelligent (microprocessor-based) adapter to reduce interrupt overhead and increase throughput.

Windows NT is a Win32 (32-bit) environment and Windows 3.x for DOS is a Win16 (16-bit) environment. Windows NT runs Win16 applications through a process called WOW (Win16 on Win32), translating 16-bit applications in enhanced mode. This process causes Win16 applications to consume additional system resources, which reduces the number of users per processor by 20% and increases the memory required per user by 25%. For this reason, Win32 versions of applications should be used whenever possible. If you intend to run Win16 applications, adjust your processor and memory requirements accordingly.
