Evaluation of Windows 7 RC Build 7100

By

Muswera Walter

Supervisor: Mr John Ebden

Consultants: Billy Morgan and Jill Japp


Background

Background

  • Vista was not received warmly due to bugs, crashes, poor performance and software incompatibility and demand for system resources

  • Microsoft has been working on a new Operating System (OS)

  • Available release at time of evaluation was Windows 7 RC Build 7100 (May 2009)


Motivation

Motivation

Claims have been made about improvements that have been made on Windows 7 since the XP era and the ill fated Vista era:

  • Security

  • Software compatibility

  • Enhanced performance (graphics, disk I/O, robustness etc)

  • Ease and speed of installation

  • Fast start-up and shutdown time

  • User friendliness

    This assessment was carried out to validate some of these claims


Importance of this research

Importance of this Research

Every new OS should be tested/evaluated before being deployed at full scale to allow for:

  • Planning of transition (upgrade and training)

  • Avert loss of time and revenue through crashes and incompatibilities

  • Evaluate availability of system support


Features evaluated

Features Evaluated

  • Security

  • Virtualisation

  • Software compatibility

  • Performance benchmarking


Evaluation of windows 7 rc build 7100

Minimum System Requirements for Windows 7

  • 1 GHz 32-bit or 64-bit processor

  • 1 GB of system memory

  • 16 GB of available disk space

  • support for DirectX 9 graphics with 128 MB memory (to enable the Aero theme)

  • DVD-R/W Drive

  • Internet access for updates

    Same as Vista

  • Specifications of Experimental Machine

  • Intel Core 2 Quad processor (Q9400 - 2.66GHz, 6MB L2 cache)

  • 4GB RAM

  • 500GB SATA hard drive with 32MB cache

  • 256MB graphics with DirectX 10 support

  • DVI and VGA connector

  • DVD writer with LightScribe

  • G45M Digital motherboard with 1GB network port


Testing conditions

Testing Conditions

  • The same computer hardware was used for all tests

  • Both OS were installed fresh in a dual boot setup

  • Results obtained reflect what you get when you install a plain OS without any tweaks or configuration changes (standard install)

  • Install time was measured from the moment the option to boot from CD/DVD was chosen until the point where the desktop reached.

  • Windows 7 Ultimate (32bit RCBuild 7100)

  • XP Professional (32bit SP3)


Security

Security

  • Bitlocker and Bitlocker To Go

    • 100MB partition

    • TPM and PCR

    • Usability on other PCs running other Oses

    • Bitlocker To Go Reader

  • UAC

    • Implementation of the 4 new levels

    • Is it really secure?


Virtualisation

Virtualisation

  • Windows XP Mode

  • consists of two things:

    • the Windows Virtual PC engine

    • a licensed copy of Windows XP SP3

  • System requirements

    • 2GB of memory

    • 15GB disk space/virtual machine


Software compatibility tests

Software Compatibility tests

  • Successful Installations

  • Compatibility issues

    • Drivers (TPM)

    • Nero 7 (program has known compatibility issues)

    • Daemon Tools (program blocked due to compatibility issues)


T ests carried out on xp sp3 and windows 7

Tests carried out on XP SP3 and Windows 7

  • Performance benchmarking

  • Installation time for each operating system

  • Logon, boot up and shutdown time


P erformance

Performance

  • PassmarkPerformanceTest version 7.0 was used to assess perfomance

    • CPU test suite is designed to measure CPU operations

    • Memory test suite is designed to exercise the memory sub-system of the computer.

    • Disk test suite is designed to measure the rate at which files are read and written from and to disk

    • 2D Graphics test suite tests of standard two dimensional graphical functions

    • 3D Graphics test suite measures the performance of the 3D graphics


Cpu tests

CPU Tests

  • Units of Measurement

  • Integer - Millions of operations per second

  • Floating Point - Millions of operations per second

  • Find Prime numbers

  • Thousands of Primes per second

  • Compression - Kilobytes Processed per second

  • Physics - Frames per second

  • Random String Sorting - Thousand Strings per second


Memory tests

Memory Tests

  • Units of Measurement

  • Cached - Megabytes transferred per second

  • Uncached - Megabytes transferred per second

  • Write - Megabytes transferred per second

  • Allocate small block- Megabytes transferred per second

  • Large RAM - Operations per second


Disk tests

DiskTests

  • Units of Measurement

  • Disk Sequential Write - Megabytes transferred per second

  • Disk Sequential Read - Megabytes transferred per second

  • Disk Random Seek + RW - Megabytes transferred per second


2d graphics tests

2D Graphics Tests

  • Units of Measurement

  • Solid Vectors - Thousands of vectors drawn per second

  • Transparent Vectors - Thousands of vectors drawn per second

  • Complex Vectors- Complex vectors drawn per second

  • Fonts and Text - Operations per second

  • Windows Interface Operations per second

  • Image Filters - Filters per second

  • Image Rendering- Images per second


3d graphics tests

3D Graphics Tests

  • Units of Measurement

  • Simple - Frames per second

  • Medium - Frames per second

  • Complex - Frames per second.

  • DirectX 11 issues on complex graphics test


Summary of findings

Summary of Findings

  • BitLockerDrive Encryption and Bitlocker To Go in Windows 7 require special hardware

  • XP Mode also requires special hardware

  • BitLocker Drive Encryptionand BitlockerTo Go are only available in the Ultimate and Enterprise Editions

  • XP Mode is available only in the Professional, Ultimate and Enterprise Editions

  • Windows 7 is incompatible with some software

  • Windows XP dominated most of the benchmarks run

  • Windows 7 performs better in the 3D graphics


Conclusions

Conclusions

  • XP still remains a better desktop OS since:

    • it has few application compatibility issues

    • works on ordinary hardware and

    • has a better performance.

  • disadvantage of “black box” benchmarking is that it cannot conclusively explain all of the performance differences

    • it merely exposes the differences
